Accounting Policies [Abstract]
OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview. Keysight Technologies, Inc. ("we," "us," "Keysight" or the "company"), incorporated in Delaware on December 6, 2013, is a technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world by providing electronic design and test solutions that are used in the simulation, design, validation, manufacture, installation, optimization and secure operation of electronics systems in the communications, networking and electronics industries. We also offer customization, consulting and optimization services throughout the customer's product lifecycle, including start-up assistance, asset management, up-time services, application services and instrument calibration and repair. Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters. Basis of Presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. ("GAAP") have been condensed or omitted pursuant to such rules and regulations. The accompanying financial statements and information should be read in conjunction with our Annual Report on Form 10-K. In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to state fairly our financial position as of July 31, 2020 and October 31, 2019, our results of operations for the three and nine months ended July 31, 2020 and 2019 and cash flows for the nine months ended July 31, 2020 and 2019 . Use of Estimates. The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Due to the COVID-19 pandemic, there has been uncertainty and disruption in the global economy and our markets. We are not aware of any specific event or circumstance that would require an update to our estimates or judgments or a revision of the carrying value of our assets or liabilities as of July 31, 2020 . Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, share-based compensation, retirement and post-retirement plan assumptions, valuation of goodwill and other intangible assets, warranty, loss contingencies, restructuring, and accounting for income taxes. Update to Significant Accounting Policies. Except as set forth in Note 2, "New Accounting Pronouncements," there have been no material changes to our significant accounting policies as described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2019 .

NEW ACCOUNTING PRONOUNCEMENTS

Accounting Standards Update and Change in Accounting Principle [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	2. NEW ACCOUNTING PRONOUNCEMENTS In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02 or Accounting Standards Codification Topic 842, Leases (“ASC 842”), that requires substantially all leases to be reported on the balance sheet as right-of-use (“ROU”) assets and lease obligations and also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. Consistent with current GAAP, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. We adopted the standard on November 1, 2019, using the modified retrospective transition approach provided by ASU 2018-11, Leases: Targeted Improvements , with the cumulative effect of initially applying the standard recognized at the date of adoption. Under this method of adoption, comparative information has not been restated and continues to be reported under the standards in effect (ASC 840) for the prior periods presented. Adoption of the standard resulted in recording ROU assets and lease obligations for our operating leases of approximately $155 million and $164 million , respectively, but did not have a material impact on beginning retained earnings, the condensed consolidated statement of operations, cash flows, or earnings per share. We elected the package of practical expedients for leases that commenced before the effective date of ASC 842, whereby we elected to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. In addition, we have lease agreements with lease and non-lease components, and we have elected the practical expedient for all underlying asset classes and account for them as a single lease component. Our finance lease and lessor arrangements are immaterial. ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. In August 2018, the FASB issued guidance that requires a customer in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to defer and recognize as an asset and aligns the recognition of implementation costs to those incurred in an arrangement that includes an internal-use software license. Further, new disclosures about implementation costs for both internal-use software and hosting arrangements are required. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our consolidated financial statements due to the adoption of this guidance. Other amendments to GAAP that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our consolidated financial statements upon adoption.

REVENUE Disaggregation of Revenue We disaggregate our revenue from contracts with customers by geographic region, end market, and timing of transfer of products and services to customers, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Disaggregated revenue is presented for each of our reportable segments.

In addition, we defer and capitalize certain costs incurred to obtain a contract (contract costs). Contract assets - Contract assets represent unbilled amounts from arrangements for which we have performed by transferring goods or services to the customer in advance of receiving all or partial consideration for such goods and services from the customer. Contract assets arise primarily from service agreements and products delivered pending a formal customer acceptance, which generally occurs within 30 days. The contract assets balance was $56 million and $34 million at July 31, 2020 and October 31, 2019, respectively, and is included in "accounts receivables, net" in our condensed consolidated balance sheet. Contract costs - We recognize an asset for the incremental costs of obtaining a contract with a customer. We have determined that certain employee and third-party representative commissions programs meet the requirements to be capitalized. Employee commissions are based on the achievement of order volume compared to a sales target. Third-party representative commission costs relate directly to a customer contract as the commission is tied to orders contracted through and contracts arranged by our third-party representatives. Without obtaining the contracts, the commissions would not be paid and, as such, are determined to be an incremental cost to obtaining a contract. We only defer these costs when we have determined the commissions are, in fact, incremental and would not have been incurred absent the customer contract. Capitalized incremental costs are allocated to the individual performance obligations in proportion to the transaction price allocated to each performance obligation and amortized based on the pattern of performance for the underlying performance obligation. Contract costs related to initial contracts and renewals are amortized over the same period because the commissions paid on both the initial contract and renewals are commensurate with one another. The following table provides a roll-forward of our capitalized contract costs, current and non-current: Nine Months Ended July 31, 2020 July 31, 2019 (in millions) Beginning balance $ 28 $ — Costs capitalized on November 1, 2018 due to ASC 606 adoption — 29 Costs capitalized during the period 49 47 Costs amortized during the period (50 ) (50 ) Ending balance $ 27 $ 26 Contract liabilities - Our contract liabilities consist of deferred revenue that arises when we receive consideration in advance of providing the goods or services promised in the contract. Contract liabilities are primarily generated from customer deposits received in advance of shipments for products or rendering of services and are recognized as revenue when services are provided to the customer. We classify deferred revenue as current or non-current based on the timing of when we expect to recognize revenue. Contract liabilities are recognized as revenue when services are provided to the customer. The following table provides a roll-forward of our contract liabilities, current and non-current: Nine Months Ended July 31, 2020 (in millions) Balance at October 31 $ 510 Deferral of revenue billed in current period, net of recognition 322 Deferred revenue arising out of acquisitions 10 Revenue recognized that was deferred as of the beginning of the period (287 ) Foreign currency translation impact 4 Balance at July 31 $ 559 Of the $287 million of revenue recognized in the nine months ended July 31, 2020 that was deferred as of the beginning of the period, approximately $64 million was recognized in the three months ended July 31, 2020. Remaining Performance Obligations Revenue expected to be recognized in any future period related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, was approximately $332 million as of July 31, 2020 , and represents the company’s obligation to deliver products and services and obtain customer acceptance on delivered products. Since we typically invoice customers at contract inception, this amount is included in our current and long-term deferred revenue balances. As of July 31, 2020 , we expect to recognize 14% of the revenue related to these unsatisfied performance obligations during the remainder of 2020 , 44% during 2021 , and 42% thereafter.

Share-based Payment Arrangement, Noncash Expense [Abstract]
SHARE-BASED COMPENSATION	4. SHARE-BASED COMPENSATION Keysight accounts for share-based awards in accordance with the provisions of the authoritative accounting guidance, which requires the measurement and recognition of compensation expense for all share-based payment awards made to our employees and directors, including restricted stock units ("RSUs"), employee stock purchases made under our Employee Stock Purchase Plan (“ESPP”), employee stock option awards, and performance share awards granted to selected members of our senior management under the Long-Term Performance (“LTP”) Program, based on estimated fair values. Three Months Ended Nine Months Ended July 31, July 31, 2020 2019 2020 2019 (in millions) Cost of products and services $ 4 $ 2 $ 13 $ 11 Research and development 4 4 15 13 Selling, general and administrative 11 10 45 42 Total share-based compensation expense $ 19 $ 16 $ 73 $ 66 At both July 31, 2020 and 2019, there was no share-based compensation capitalized within inventory. The total shareholder return (TSR) based performance awards are valued using a Monte Carlo simulation model, which requires the use of highly subjective and complex assumptions, including the price volatility of the underlying stock. The valuation is done once every year in the first quarter at the time of annual grants. The estimated fair value of restricted stock awards and the financial metrics-based performance awards is determined based on the market price of Keysight’s common stock on the grant date. The compensation cost for financial metrics-based performance awards reflects the cost of awards that are probable to vest at the end of the performance period. We did not grant option awards in the three and nine months ended July 31, 2020 and 2019.

Income Tax Disclosure [Abstract]
INCOME TAXES	5. INCOME TAXES The company’s effective tax rate was 4.7 percent and 17.2 percent for the three and nine months ended July 31, 2020, respectively. The income tax expense was $9 million and $85 million for the three and nine months ended July 31, 2020, respectively. The income tax expense for the three and nine months ended July 31, 2020 included a net discrete benefit of $10 million and $5 million , respectively. The company’s effective tax rate was 20.1 percent and 16.9 percent for the three and nine months ended July 31, 2019, respectively. The income tax expense was $40 million and $86 million for the three and nine months ended July 31, 2019, respectively. The income tax expense for the three and nine months ended July 31, 2019 included a net discrete benefit of $3 million and $32 million , respectively. The net discrete benefit for the nine months ended July 31, 2019 primarily related to a change in tax reserves resulting from a change in judgment. Keysight benefits from tax incentives in several jurisdictions, most significantly in Singapore, that have granted us tax incentives that require renewal at various times in the future. The tax incentives provide lower rates of taxation on certain classes of income and require thresholds of investments and employment or specific types of income in those jurisdictions. The impact of the tax incentives decreased the income tax provision by $29 million and $32 million for the nine months ended July 31, 2020 and 2019, respectively, resulting in a benefit to net income per share (diluted) of approximately $0.15 and $0.17 for the nine months ended July 31, 2020 and 2019, respectively. The majority of our tax incentives are due for renewal between 2024 and 2025. With regard to the incentive in Malaysia, a formal application must be filed during fiscal year 2020 to renew the tax incentive through 2025. Keysight intends to file the application timely and does not anticipate any impediments to the renewal process. The open tax years for the IRS and most states as of July 31, 2020 are from November 1, 2015 through the current tax year. For the majority of our foreign entities, the open tax years are from November 1, 2014 through the current tax year. For certain foreign entities, the tax years remain open, at most, back to the year 2008 . Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, we are unable to estimate the range of possible changes to the balance of our unrecognized tax benefits. The company was audited in Malaysia for the 2008 tax year. This tax year pre-dates our separation from Agilent. However, pursuant to the tax matters agreement between Agilent and Keysight that was finalized at the time of separation, for certain entities, including Malaysia, any historical tax liability is the responsibility of Keysight. In the fourth quarter of fiscal 2017, Keysight paid income taxes and penalties to the Malaysian Tax Authority of $68 million on gains related to intellectual property rights. Our appeal to the Special Commissioners of Income Tax in Malaysia was unsuccessful. An appeal has now been lodged with the High Court. The company believes there are numerous defenses to the current assessment; the statute of limitations for the 2008 tax year in Malaysia was closed, and the income in question is exempt from tax in Malaysia. The company is pursuing all avenues to resolve this issue favorably for the company. In response to the COVID-19 outbreak, various jurisdictions in which the company operates have enacted emergency economic stimulus packages that contain certain income tax provisions. This includes the U.S. federal government enactment of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) on March 27, 2020. Although the company continues to evaluate the impact of such legislation, we have not identified any material impacts on the income tax provision. The company will continue to monitor the impact of these stimulus packages as new clarifying guidance is issued or as additional legislation is enacted.

Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense are collectively assumed to be used to repurchase hypothetical shares. We exclude stock options with exercise prices greater than the average market price of our common stock from the calculation of diluted earnings per share because their effect would be anti-dilutive. For both the three and nine months ended July 31, 2020 and 2019, we excluded zero options from the calculation of diluted earnings per share. In addition, we also exclude from the calculation of diluted earnings per share, stock options, ESPP, LTP Program and restricted stock awards, whose combined exercise price and unamortized fair value collectively were greater than the average market price of our common stock because their effect would also be anti-dilutive. The number of shares excluded was not material for the three and nine months ended July 31, 2020. For the three and nine months ended July 31, 2019, we excluded approximately 336,000 shares and 253,000 shares, respectively.

GOODWILL AND OTHER INTANGIBLE ASSETS The goodwill balances as of July 31, 2020 and October 31, 2019 and the activity for the nine months ended July 31, 2020 for each of our reportable operating segments were as follows. Prior period amounts have been reclassified to conform to our organizational change as described in Note 17, "Segment Information." Communications Solutions Group Electronic Industrial Solutions Group Total (in millions) Balance as of October 31, 2019: Goodwill $ 1,651 $ 267 $ 1,918 Accumulated impairment losses (709 ) — (709 ) Goodwill as reported 942 267 1,209 Goodwill arising from acquisitions 8 280 288 Foreign currency translation impact 6 7 13 Balance as of July 31, 2020 $ 956 $ 554 $ 1,510 Components of goodwill as of July 31, 2020: Goodwill $ 1,665 $ 554 $ 2,219 Accumulated impairment losses (709 ) — (709 ) Goodwill as reported $ 956 $ 554 $ 1,510 During the third quarter of fiscal 2020, we acquired Eggplant Topco Limited ("Eggplant") for $319 million , net of $11 million cash acquired, and recognized additions to goodwill and other intangible assets of $280 million and $88 million , respectively, based on the preliminary allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed. The identified intangible assets primarily consist of developed technology of $38 million and customer relationships of $46 million with estimated useful lives of 3 years and 6 years , respectively. Eggplant is a software test automation platform provider that uses artificial intelligence and analytics to automate test creation and test execution. Goodwill was assessed for impairment upon the completion of the organizational change in the first quarter of fiscal 2020, and it was determined that it was more-likely-than-not that the fair value of the reporting unit was greater than its carrying value. We evaluated the impact of the deterioration in overall global economic conditions as a result of the COVID-19 pandemic, including the change in our market capitalization and changes in forecasts for each reporting unit, and we determined that no triggering events had occurred as of July 31, 2020. Other intangible assets as of July 31, 2020 and October 31, 2019 consisted of the following: Other Intangible Assets as of July 31, 2020 Other Intangible Assets as of October 31, 2019 Gross Carrying Amount Accumulated Amortization Net Book Value Gross Carrying Amount Accumulated Amortization Net Book Value (in millions) Developed technology $ 916 $ 705 $ 211 $ 876 $ 578 $ 298 Backlog 17 13 4 13 13 — Trademark/Tradename 34 24 10 34 21 13 Customer relationships 363 171 192 316 139 177 Non-compete agreements 1 1 — 1 1 — Total amortizable intangible assets 1,331 914 417 1,240 752 488 In-Process R&D 2 — 2 2 — 2 Total $ 1,333 $ 914 $ 419 $ 1,242 $ 752 $ 490 During the nine months ended July 31, 2020 , there was $3 million foreign exchange translation impact to other intangible assets.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	10. FAIR VALUE MEASUREMENTS The authoritative guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability. Fair Value Hierarchy The guidance establishes a fair value hierarchy that prioritizes inputs used in valuation techniques into three levels. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value: Level 1 - applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 - applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, for the asset or liability such as: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in less active markets; or other inputs that can be derived principally from, or corroborated by, observable market data. Level 3 - applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities measured at fair value on a recurring basis as of July 31, 2020 and October 31, 2019 were as follows: Fair Value Measurements at July 31, 2020 October 31, 2019 Total Level 1 Level 2 Level 3 Other Total Level 1 Level 2 Level 3 Other (in millions) Assets: Short-term Cash equivalents Money market funds $ 1,054 $ 1,054 $ — $ — $ — $ 932 $ 932 $ — $ — $ — Derivative instruments (foreign exchange contracts) 7 — 7 — — 2 — 2 — — Long-term Equity investments 52 52 — — — 37 37 — — — Equity investments - other 9 — — — 9 9 — — — 9 Total assets measured at fair value $ 1,122 $ 1,106 $ 7 $ — $ 9 $ 980 $ 969 $ 2 $ — $ 9 Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 9 $ — $ 9 $ — $ — $ 6 $ — $ 6 $ — $ — Long-term Deferred compensation liability 17 — 17 — — 14 — 14 — — Derivative instruments (interest rate swaps) 7 — 7 — — — — — — — Total liabilities measured at fair value $ 33 $ — $ 33 $ — $ — $ 20 $ — $ 20 $ — $ — Net recognized gains (losses) on equity investments were as follows: Three Months Ended Nine Months Ended July 31, July 31, 2020 2019 2020 2019 (in millions) Net realized gains on investments sold $ — $ — $ — $ 1 Net unrealized gains (losses) in investments still held 3 4 13 7 Total $ 3 $ 4 $ 13 $ 8 Our money market funds and equity investments with readily determinable fair values are measured at fair value using quoted market prices and, therefore, are classified within Level 1 of the fair value hierarchy. Equity investments without readily determinable fair values that are measured at cost adjusted for observable changes in price or impairments are not categorized in the fair value hierarchy and are presented as "Equity investments - other" in the table above. Our deferred compensation liability is classified as Level 2 because the inputs used in the calculations are observable, although the values are not directly based on quoted market prices. Our derivative financial instruments are classified within Level 2 as there is not an active market for each hedge contract, but the inputs used to calculate the value of the instruments are tied to active markets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	11. DERIVATIVES We are exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal course of our business. As part of our risk management strategy, we use derivative instruments, primarily forward contracts to hedge economic and/or accounting exposures resulting from changes in foreign currency exchange rates. Cash Flow Hedges We enter into foreign exchange contracts to hedge our forecasted operational cash flow exposures resulting from changes in foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities between one and fourteen months. The changes in the fair value of the effective portion of the derivative instrument are recognized in accumulated other comprehensive income (loss) and reclassified into earnings when the forecasted transaction occurs in the same financial statement line item in the condensed consolidated statement of operations where the earnings effect of the hedged item is presented. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive income (loss) will be reclassified into earnings in the current period. Gains and losses on the derivative instrument representing hedge components excluded from the assessment of effectiveness are presented in the same financial statement line of the condensed consolidated statement of operations where the earnings effect of the hedged item is presented. For hedges executed prior to February 1, 2020, these gains and losses are recognized immediately in earnings while for any new hedges, they are amortized on a straight line basis over the tenor of the hedge. During the second quarter of 2020, we entered into forward starting interest rate swaps with an aggregate notional amount of $600 million associated with future interest payments on anticipated debt issuances through fiscal year 2024. The contract term allows us to lock-in a treasury rate on anticipated debt issuances. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. The changes in fair value of these derivative instruments have been recognized in accumulated other comprehensive income (loss). For the three and nine months ended July 31, 2020, a loss of $3 million and $7 million , respectively, was recognized in accumulated other comprehensive income (loss). Amounts associated with these cash flow hedges will be reclassified to interest expense in the condensed consolidated statement of operations when future interest payments on the anticipated debt occur. Non-designated Hedges Additionally, we enter into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of our subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in value of the derivative are recognized in other income (expense), net, in the condensed consolidated statement of operations in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities. Our use of derivative instruments exposes us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We do, however, seek to mitigate such risks by limiting our counterparties to major financial institutions that are selected based on their credit ratings and other factors. We have established policies and procedures for mitigating credit risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties. The number of open foreign exchange forward contracts designated as "cash flow hedges" and "not designated as hedging instruments" was 193 and 62 , respectively, as of July 31, 2020 . The aggregated notional amounts by currency and designation as of July 31, 2020 were as follows: Derivatives in Cash Flow Hedging Relationships Derivatives Not Designated as Hedging Instruments Forward Contracts Forward Contracts Currency Buy/(Sell) Buy/(Sell) (in millions) Euro $ 17 $ 59 British Pound — (75 ) Singapore Dollar 18 11 Malaysian Ringgit 82 9 Japanese Yen (78 ) (68 ) Other currencies (17 ) 9 Total $ 22 $ (55 ) Derivative instruments are subject to master netting arrangements and are disclosed gross in the condensed consolidated balance sheet.

We did not contribute to our U.S. Defined Benefit Plans or U.S. Post-Retirement Benefit Plan during the three and nine months ended July 31, 2020 and 2019. We contributed $2 million and $6 million to our Non-U.S. Defined Benefit Plans during the three and nine months ended July 31, 2020, respectively, and we contributed $6 million and $21 million to our Non-U.S. Defined Benefit Plans during the three and nine months ended July 31, 2019, respectively. For the remainder of 2020 , we are evaluating potential contributions to our U.S. Defined Benefit Plans, although a contribution is not required, and we expect to contribute $2 million to our Non-U.S. Defined Benefit Plans. On January 1, 2019 , we transferred a portion of the assets and liabilities of our Switzerland defined benefit plan to an insurance company, resulting in the recognition of a settlement loss of $2 million , which is included in other income (expense), net in the condensed consolidated statement of operations.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	13. LEASES We determine whether an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities (current and non-current) on our condensed consolidated balance sheet. Finance leases are included in property, plant and equipment, other accrued liabilities, and other long-term liabilities in our condensed consolidated balance sheet. Our finance lease and lessor arrangements are immaterial. ROU assets and lease obligations are recognized based on their present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the lease term and economic environment to discount lease obligations. ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. We initially measure payments based on an index by using the applicable rate at lease commencement. Variable payments that do not depend on an index are not included in the lease liability and are recognized as they are incurred. We have operating leases for items including office space, order fulfillment, sales and service centers, R&D and certain equipment, primarily automobiles. Our leases have remaining terms of up to 14 years, some of which may include options to extend the leases for 3 to 6 years. We consider options to renew in our lease terms and measurement of ROU assets and lease liabilities if we determine they are reasonably certain to be exercised. As of July 31, 2020, the weighted average lease term of our operating leases was 7.4 years and the weighted average discount rate of our operating leases was 3% . Operating lease cost for the three and nine months ended July 31, 2020 was $13 million and $36 million , respectively, and variable lease cost was $4 million and $12 million , respectively. Short-term lease and finance lease costs were immaterial for both the three and nine months ended July 31, 2020. Supplemental cash flow information related to leases was as follows: Nine Months Ended July 31, 2020 (in millions) Cash paid for amounts included in the measurement of lease liabilities — operating cash flows $ 35 ROU assets obtained in exchange for operating lease obligations $ 62 Amounts related to finance lease activities for the nine months ended July 31, 2020 were not material.

Commitments and Contingencies Disclosure [Abstract]
WARRANTY, COMMITMENTS AND CONTINGENCIES	14. WARRANTIES, COMMITMENTS AND CONTINGENCIES Standard Warranty Our warranties on products sold through direct sales channels are primarily for one year. Warranties for products sold through distribution channels are primarily for three years. We accrue for standard warranty costs based on historical trends in warranty charges.

In addition, the Revolving Credit Facility permits us to increase the total commitments under this credit facility by up to $150 million in the aggregate on one or more occasions upon request. We may use amounts borrowed under the facility for general corporate purposes. As of July 31, 2020 and October 31, 2019, we had no borrowings outstanding under the Revolving Credit Facility. We were in compliance with the covenants of the Revolving Credit Facility during the nine months ended July 31, 2020. Other During the three and nine months ended July 31, 2020, we repaid $7 million of debt assumed with the acquisition of Eggplant. Long-Term Debt There have been no changes to the principal, maturity, interest rates and interest payment terms of the senior notes during the nine months ended July 31, 2020 as compared to the senior notes described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2019. As of July 31, 2020 and October 31, 2019, we had $36 million and $37 million , respectively, of outstanding letters of credit and surety bonds unrelated to the credit facility that were issued by various lenders. The fair value of our long-term debt, calculated from quoted prices that are primarily Level 1 inputs under the accounting guidance fair value hierarchy, exceeded the carrying value by approximately $270 million and $139 million as of July 31, 2020 and October 31, 2019, respectively. The increase in fair value is due to low U.S. Treasury yields combined with declining corporate credit spreads.

Segment Reporting [Abstract]
SEGMENT INFORMATION	17. SEGMENT INFORMATION We are a technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world by providing electronic design and test solutions that are used in the simulation, design, validation, manufacture, installation, optimization and secure operation of electronics systems in the communications, networking and electronics industries. We also offer customization, consulting and optimization services throughout the customer's product lifecycle, including start-up assistance, asset management, up-time services, application services and instrument calibration and repair. Our operating segments were determined based primarily on how the chief operating decision maker views and evaluates our operations. Segment operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to each segment and to assess performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and services and manufacturing are considered in determining the formation of these operating segments. We completed an organizational change in the first quarter of fiscal 2020 to manage our Ixia Solutions Group within our Communications Solutions Group to enable us to create improved go-to market and product development alignment as well as accelerate solution synergies as new technologies emerge. Prior period segment results were revised to conform to the presentation. As a result, we now have two reportable operating segments, Communications Solutions Group (“CSG”) and Electronic Industrial Solutions Group (“EISG”). T he Communications Solutions Group serves customers spanning the worldwide commercial communications and aerospace, defense, and government end markets. The group’s solutions consist of electronic design and test software, electronic measurement instruments, systems and related services. These solutions are used in the simulation, design, validation, manufacturing, installation, and optimization of electronic equipment and networks. The Electronic Industrial Solutions Group provides test and measurement solutions and related services across a broad set of electronic industrial end markets, focusing on high-value applications in the automotive and energy industry and measurement solutions for consumer electronics, education, general electronics design and manufacturing, and semiconductor design and manufacturing. The group provides electronic design and test software, electronic measurement instruments and systems and related services used in the simulation, design, validation, manufacturing, installation and optimization of electronic equipment. A significant portion of the segments' expenses arise from shared services and infrastructure that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include legal, accounting, real estate, insurance services, information technology services, treasury and other corporate infrastructure expenses. Charges are allocated to the segments, and the allocations have been determined on a basis that we considered to be a reasonable reflection of the utilization of services provided to or benefits received by the segments. The following tables reflect the results of our reportable segments under our management reporting system. These results are not necessarily in conformity with GAAP. The performance of each segment is measured based on several metrics, including income from operations. These results are used, in part, by the chief operating decision maker in evaluating the performance of, and in allocating resources to, each of the segments. Prior period amounts have been revised to conform to the new organizational structure. The profitability of each of the segments is measured after excluding share-based compensation expense, amortization of acquisition-related balances, acquisition and integration costs, restructuring and related costs, northern California wildfire-related impacts, interest income, interest expense and other items as noted in the reconciliations below.
