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 measurement company providing electronic design and test solutions to communications and electronics industries. 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 condensed consolidated balance sheet as of January 31, 2017 and October 31, 2016 , condensed consolidated statement of comprehensive income for the three months ended January 31, 2017 and 2016 , condensed consolidated statement of operations for the three months ended January 31, 2017 and 2016 , and condensed consolidated statement of cash flows for the three months ended January 31, 2017 and 2016 . 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. 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, restructuring, and accounting for income taxes. Land Sale. On April 30, 2014 we entered into a binding contract to sell land in the United Kingdom ("U.K.") that resulted in the transfer of three separate land tracts in May 2014, November 2015 and November 2016 for £21 million . In the three months ended January 31, 2017 and 2016, we recognized gains of $8 million and $10 million , respectively, on the sale of the land tracts in other operating expense (income). Restricted Cash. As of January 31, 2017 and October 31, 2016, restricted cash of $2 million consisted of approximately $1 million of deposits held as collateral against bank guarantees and approximately $1 million of deposits primarily held as collateral against foreign currency hedging contracts and is classified within other assets and other current assets, respectively, in the condensed consolidated balance sheet. Update to Significant Accounting Policies. There have been no material changes to our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2016.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	2. NEW ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board ("FASB") issued an amendment to the accounting guidance related to revenue recognition. The amendment was the result of a joint project between the FASB and the International Accounting Standards Board ("IASB") to clarify the principles for recognizing revenue and to develop common revenue standards for GAAP and International Financial Reporting Standards ("IFRS"). To meet those objectives, the FASB amended the FASB Accounting Standards Codification and created a new Topic 606, Revenue from Contracts with Customers , and the IASB issued IFRS 15, Revenue from Contracts with Customers . On July 9, 2015, the FASB deferred the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. The FASB also permitted early adoption of the standard, but not before the original effective date of December 15, 2016. In addition, during March, April, May and December 2016 the FASB issued guidance that made technical corrections and improvements and clarified the reporting of revenue as a principal versus agent, identifying performance obligations, accounting for intellectual property licenses, narrow-scope improvements, and practical expedients. We are evaluating the impact of adopting this guidance on our consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs , to simplify the presentation of deferred issuance costs by requiring that they be presented as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The standard is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We adopted this guidance retrospectively during the first quarter of 2017. As a result, $7 million of unamortized debt issuance costs have been reclassified from other assets to long-term debt in the consolidated balance sheet as of January 31, 2017 and October 31, 2016 (see Note 14). In February 2016, the FASB issued guidance that will require organizations that lease assets to recognize assets and liabilities for leases with lease terms of more than 12 months. 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. However, unlike current GAAP, which requires only capital leases to be recognized on the balance sheet, the new guidance will require both types of leases to be recognized on the balance sheet. The standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact of adopting this guidance on our consolidated financial statements. In March 2016, the FASB issued guidance that simplifies the accounting for taxes related to share-based compensation, including adjustments to how excess tax benefits and a company's payments for tax withholdings should be classified. The standard is effective for annual and interim periods beginning after December 31, 2016. Early adoption is permitted. We are evaluating the impact of adopting this guidance on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory , that removes the requirement under which the income tax consequences of intra-entity transfers are deferred until the assets are ultimately sold to an outside party, except for transfers of inventory. The tax consequences of such transfers would be recognized in tax expense when the transfers occur. The standard is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. We elected to early adopt this guidance on a modified retrospective basis during the first quarter of 2017. As a result, a $10 million cumulative-effect adjustment was recorded directly to retained earnings as of November 1, 2016, the beginning of the annual period of adoption, with corresponding reductions of $2 million , $6 million and $2 million to other current assets, other assets, and long-term deferred tax assets, respectively. In January 2017, the FASB issued guidance to narrow the definition of a business and provide a framework that gives entities a basis for making reasonable judgments about whether a transaction involves an asset or a business. The standard is effective for fiscal years beginning after December 15, 2017, 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. In January 2017, the FASB issued guidance that eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The standard is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. 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.

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION	3 Months Ended

Share-based Compensation [Abstract]
SHARE-BASED COMPENSATION	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 employee stock option awards, restricted stock units ("RSUs"), employee stock purchases made under our Employee Stock Purchase Plan (“ESPP”) and performance share awards granted to selected members of our senior management under the Long-Term Performance (“LTP”) Program based on estimated fair values. The impact of share-based compensation on our results was as follows: Three Months Ended January 31, 2017 2016 (in millions) Cost of products and services $ 3 $ 3 Research and development 4 3 Selling, general and administrative 11 10 Total share-based compensation expense $ 18 $ 16 At January 31, 2017 and 2016 , share-based compensation capitalized within inventory was $1 million. The income tax benefit realized from the exercised stock options and similar awards recognized was $2 million and $1 million for the three months ended January 31, 2017 and 2016, respectively. The following assumptions were used to estimate the fair value of LTP Program grants. Three Months Ended January 31, 2017 2016 LTP Program: Volatility of Keysight shares 27 % 25 % Volatility of selected index (2017)/peer-company shares (2016) 15 % 14%-54% Price-wise correlation with selected peers 57 % 38 % Shares granted under the LTP Program were valued using a Monte Carlo simulation model. In the first quarter of fiscal 2017, the company began awarding an additional type of performance award based on operating margin performance. These awards were valued based on the market price of Keysight’s common stock on the date of grant. The fair value of employee stock option awards granted before October 31, 2015 was estimated using the Black-Scholes option pricing model. We did not grant any option awards for the three months ended January 31, 2017 and 2016. Both the Black-Scholes and Monte Carlo simulation fair value models require the use of highly subjective and complex assumptions, including the option’s expected life and the price volatility of the underlying stock. The estimated fair value of restricted stock awards is determined based on the market price of Keysight’s common stock on the date of grant.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The company’s effective tax rate was 28.3 percent and 23.7 percent for the three months ended January 31, 2017 and 2016, respectively. Income tax expense was $43 million and $20 million for the three months ended January 31, 2017 and 2016, respectively. The income tax provision for the three months ended January 31, 2017 and 2016 included a net discrete expense of $23 million and $1 million, respectively. The increase in the total income tax expense and discrete expense for the three months ended January 31, 2017, is primarily related to $22 million of tax resulting from the transfer of a portion of the Japanese Employees’ Pension Fund (see Note 11). Keysight benefits from tax incentives in several jurisdictions, most significantly in Singapore, and several jurisdictions 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 tax incentives decreased the income tax provision for the three months ended January 31, 2017 and 2016 by $11 million and $8 million , respectively, resulting in a benefit to net income per share (diluted) of approximately $0.07 and $0.05 for the three months ended January 31, 2017 and 2016, respectively. The Singapore tax incentive is due for renewal in fiscal 2024. For the majority of our entities, the open tax years for the IRS, state and most foreign audit authorities are from August 1, 2014 , through the current tax year. For certain foreign entities, the tax years generally remain open back to the year 2006 . 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.

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 the effect would be anti-dilutive. For the three months ended January 31, 2017 and 2016, we excluded zero and 1.7 million options, respectively, from the calculation of diluted earnings per share. In addition, we excluded stock options, ESPP shares, LTP Program and restricted stock awards, of which the combined exercise price, unamortized fair value and excess tax benefits collectively was greater than the average market price of our common stock because the effect would be anti-dilutive. For the three months ended January 31, 2017 and 2016, we excluded 424,400 and 16,100 shares, respectively.

Amortization of other intangible assets was $11 million and $12 million for the three months ended January 31, 2017 and 2016, respectively. Future amortization expense related to existing finite-lived purchased intangible assets is estimated to be $31 million for the remainder of 2017, $39 million for 2018, $38 million for 2019, $ 38 million for 2020, $30 million for 2021 and $14 million thereafter.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Jan. 31, 2017
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	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 January 31, 2017 and October 31, 2016 were as follows: Fair Value Measurements at January 31, 2017 Fair Value Measurements at October 31, 2016 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 (in millions) Assets: Short-term Cash equivalents (money market funds) $ 572 $ 572 $ — $ — $ 471 $ 471 $ — $ — Derivative instruments (foreign exchange contracts) 7 — 7 — 4 — 4 — Long-term Trading securities 11 11 — — 11 11 — — Available-for-sale investments 34 34 — — 29 29 — — Total assets measured at fair value $ 624 $ 617 $ 7 $ — $ 515 $ 511 $ 4 $ — Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 6 $ — $ 6 $ — $ 8 $ — $ 8 $ — Long-term Deferred compensation liability 11 — 11 — 11 — 11 — Total liabilities measured at fair value $ 17 $ — $ 17 $ — $ 19 $ — $ 19 $ — Our money market funds, trading securities, and available-for-sale investments are generally valued using quoted market prices and therefore are classified within Level 1 of the fair value hierarchy. 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. Our deferred compensation liability is classified as Level 2 because, although the values are not directly based on quoted market prices, the inputs used in the calculations are observable. Trading securities and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale and certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income (loss). Realized gains and losses from the sale of these instruments are recorded in earnings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	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 and purchased options, 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 twelve months. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. Ineffectiveness in the three months ended January 31, 2017 and 2016 was not significant . Other 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. 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. A number of our derivative agreements contain threshold limits to the net liability position with counterparties and are dependent on our corporate credit rating determined by the major credit rating agencies. The counterparties to the derivative instruments may request collateralization, in accordance with derivative agreements, on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position as of January 31, 2017 was $4 million . The credit-risk-related contingent features underlying these agreements had not been triggered as of January 31, 2017 . There were 137 foreign exchange forward contracts open as of January 31, 2017 that were designated as cash flow hedges. There were 60 foreign exchange forward contracts as of January 31, 2017 that were not designated as hedging instruments. The aggregated notional amounts by currency and designation as of January 31, 2017 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 $ — $ 62 British Pound — 10 Singapore Dollar 10 1 Malaysian Ringgit 70 1 Japanese Yen (82 ) (41 ) Other currencies (15 ) 6 Total $ (17 ) $ 39 Derivative instruments are subject to master netting arrangements and are disclosed gross in the balance sheet in accordance with the authoritative guidance.

Debt Disclosure [Abstract]
DEBT	DEBT Short-Term Debt On January 30, 2017 , we entered into a commitment letter, pursuant to which certain lenders have agreed to provide a senior unsecured 364 -day bridge loan facility of up to $1.684 billion (“the Bridge Facility”) for the purpose of providing the financing to support Keysight's acquisition of Ixia. The company incurred issuance costs of $8 million in connection with the Bridge Facility. These costs are included in other current assets in the condensed consolidated balance sheet and are being amortized to interest expense over the term of the Bridge Facility. In connection with entering into the term credit agreement (described below), on February 15, 2017, the unsecured commitments under the Bridge Facility were automatically reduced in an aggregate principal amount of $400 million . On February 15, 2017 , we entered into an amended and restated credit agreement (the “Revolving Credit Facility”) that provides for a $450 million five-year unsecured revolving credit facility that will expire on February 15, 2022 . 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. The Revolving Credit Facility replaced our existing $450 million unsecured credit facility, dated as of September 15, 2014. The company may use amounts borrowed under the facility for general corporate purposes, including to finance, in part, the acquisition of Ixia, the payment of fees and expenses related thereto and the repayment in full of all third-party indebtedness of Ixia and its subsidiaries that becomes due or otherwise defaults upon the consummation of the Ixia acquisition. As of January 31, 2017, we had no borrowings outstanding under the Revolving Credit Facility. We were in compliance with the covenants of the Revolving Credit Facility during the three months ended January 31, 2017. Long-Term Debt The following table summarizes the components of our long-term debt: January 31, 2017 October 31, 2016 (in millions) 3.30% Senior Notes due 2019 $ 497 $ 497 4.55% Senior Notes due 2024 596 596 Total $ 1,093 $ 1,093 The notes issued are unsecured and rank equally in right of payment with all of our other senior unsecured indebtedness. There were no changes to the principal, maturity, interest rates and interest payment terms of the senior notes during the three months ended January 31, 2017 . On February 15, 2017 , we entered into a term credit agreement, which provides for a three -year $400 million delayed draw senior unsecured term loan facility. The term loans will be available to us upon the closing of the Ixia acquisition. The term loan is intended to be used to finance, in part, the Ixia acquisition, the payment of fees and expenses related thereto and the repayment in full of all third-party indebtedness of Ixia and its subsidiaries that becomes due or otherwise defaults upon the consummation of the Ixia acquisition. The commitments under the term credit agreement automatically terminate on the first to occur of (a) the consummation of the Ixia acquisition without the borrowing of any loans under the term credit agreement, (b) the termination of the Merger Agreement to acquire Ixia in accordance with its terms or (c) on October 30, 2017. See Note 17 for further details regarding the pending acquisition. As of January 31, 2017 and October 31, 2016, we had $19 million and $18 million , respectively, of outstanding letters of credit unrelated to the credit facility that were issued by various lenders.

SEGMENT INFORMATION

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION We provide electronic design and test instruments and systems and related software, software design tools, and related services that are used in the design, development, manufacture, installation, deployment and operation of electronics equipment. Related services include start-up assistance, instrument productivity and application services and instrument calibration and repair. We also offer customization, consulting and optimization services throughout the customer's product lifecycle. In fiscal 2016, we completed an organizational change to align our organization with the industries we serve. As a result of this organizational realignment, we have three reportable operating segments, Communications Solutions Group (“CSG”), Electronic Industrial Solutions Group (“EISG”), and Services Solutions Group (“SSG”). CSG and EISG are from our previous Measurement Solutions segment, while SSG was formerly reported as the company's Customer Support and Services segment. The new organizational structure continues to include centralized enterprise functions that provide support across the groups. Prior period amounts were revised to conform to the current presentation. Our three 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. Descriptions of our three reportable segments are as follows: The Communications Solutions Group serves customers spanning the worldwide commercial communications end market, which includes internet infrastructure, and the aerospace, defense and government end market. The group provides electronic design and test software, instruments, and systems used in the simulation, design, validation, manufacturing, installation and optimization of electronic equipment. The Electronic Industrial Solutions Group provides test and measurement solutions across a broad set of electronic industrial end markets, focusing on high-growth applications in the automotive and energy industry and measurement solutions for semiconductor design and manufacturing, consumer electronics, education and general electronics manufacturing. The group provides electronic design and test software, instruments, and systems used in the simulation, design, validation, manufacturing, installation and optimization of electronic equipment. The Services Solutions Group provides repair, calibration and consulting services, and remarkets used Keysight equipment. In addition to providing repair and calibration support for Keysight equipment, we also calibrate non-Keysight equipment. The group serves the same markets as Keysight’s Communications Solutions and Electronic Industrial Solutions Groups, providing industry-specific services to deliver complete Keysight solutions and help customers reduce their total cost of ownership for their design and test 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 costs of centralized research and development, 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 consider 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. The profitability of each of the segments is measured after excluding share-based compensation expense, restructuring and asset impairment charges, investment gains and losses, interest income, interest expense, acquisition and integration costs, separation and related costs, acquisition-related fair value adjustments, non-cash amortization and other items as noted in the reconciliations below.
