Exhibit 99.1

Ixia Announces Record First Quarter 2012 Revenue

CALABASAS, CA, April 19, 2012--Ixia (Nasdaq:XXIA) today reported its financial results for the first quarter ended March 31, 2012.

Total revenue for the 2012 first quarter was $85.6 million, compared with $78.5 million reported for the 2011 first quarter and $83.7 million reported for the 2011 fourth quarter.

On a GAAP basis, the company recorded net income for the 2012 first quarter of $4.4 million, or $0.06 per diluted share, compared with net income of $7.1 million, or $0.10 per diluted share, for the 2011 first quarter.

Non-GAAP net income for the 2012 first quarter was $11.4 million, or $0.15 per diluted share, compared with non-GAAP net income of $12.2 million, or $0.16 per diluted share, for the 2011 first quarter.

Additional non-GAAP information and a reconciliation of our non-GAAP measures to the most directly comparable GAAP measures for the 2012 and 2011 first quarters may be found in the attached financial tables.

“In the first quarter, we achieved record revenue primarily driven by a robust quarter in Japan as well as the strong sales of our LTE solutions worldwide,” commented Victor Alston, Ixia’s chief operating officer. “We are encouraged by the strong start to the year and the opportunities for growth we see in 2012. While we have seen increases in the levels of our operating expenses over the last few quarters, we believe that these investments position us well in the more rapidly growing and promising segments of our market, including virtualization, cloud, mobility and security test solutions for the converged networks of the future. These investments pave the way for Ixia to be a leader in emerging markets for the years to come.”

Ixia ended the first quarter with approximately $422 million in cash and investments, compared with $385 million at December 31, 2011.

Non-GAAP Information

To supplement our consolidated financial results prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), we have included certain non-GAAP financial measures in this press release and in the attachments hereto. Specifically, we have provided non-GAAP financial measures (e.g., non-GAAP cost of revenues, non-GAAP operating expenses, non-GAAP operating margin, non-GAAP income tax expense, non-GAAP net income, and non-GAAP diluted earnings per share) that exclude certain non-cash and/or non-recurring income and expense items such as proceeds and expenses from certain legal and contractual settlements, stock-based compensation expenses, acquisition and other related costs, the amortization of acquisition-related intangible assets, and the related income tax effects of these items, as well as the income tax impacts of the valuation allowance recorded against certain deferred tax assets. The aforementioned items represent income and expense items that may be difficult to estimate from period to period and/or that we believe are not directly attributable to the underlying performance of our business operations. These non-GAAP financial measures are provided to enhance the user’s overall understanding of our financial performance. We believe that by excluding these items, our non-GAAP measures provide supplemental information to both management and investors that is useful in assessing our core operating performance, in evaluating our ongoing business operations and in comparing our results of operations on a consistent basis from period to period. These non-GAAP financial measures are also used by management to plan and forecast future periods and to assist in making operating and strategic decisions. The presentation of this additional information is not prepared in accordance with GAAP. The information therefore may not necessarily be comparable to that of other companies and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. Investors are encouraged to review the reconciliations of GAAP to non-GAAP financial measures which are included below in the attached financial tables.

(a)

This reconciling item represents stock-based compensation expenses. As stock-based compensation represents a non-cash charge that is not directly attributable to the underlying performance of our business operations, we believe that by excluding stock-based compensation, we provide our investors with supplemental information that is useful in comparing our operating results from period to period and in evaluating our core operations and performance. While we expect to continue to recognize stock-based compensation expense in the future, management also excludes this expense when evaluating current performance, forecasting future results, measuring core operating results, and making operating and strategic decisions.

(b)

This reconciling item represents the amortization of intangible assets related to the acquisitions of various businesses and technologies such as the acquisitions of Catapult Communications Corporation, Agilent Technologies’ N2X Data Network Testing Product line and VeriWave, Inc. As the amortization expense represents a non-cash charge that is not directly attributable to the underlying performance of our business operations, we believe that by excluding the amortization of acquisition-related intangible assets, we provide investors with supplemental information that is useful in evaluating our ongoing operations and performance. While the amortization of acquisition-related intangible assets is expected to continue in the future, management also excludes this expense when evaluating current performance, forecasting future results, measuring core operating results, and making operating and strategic decisions.

(c)	This reconciling item represents costs associated with acquisition-related activities. These acquisition and other related costs consist primarily of professional fees for legal, accounting and tax services, and other related costs. We believe that by excluding acquisition and other related costs, we provide investors with supplemental information that is useful in comparing our ongoing operating results from period to period and in evaluating our core operations and performance.
(d)	This reconciling item represents a one-time charge of $900,000 incurred in the first quarter of 2011 to terminate and settle a development contract and a one-time transition charge of $1.7 million incurred in the first quarter of 2012 in connection with the previously announced departure of our CEO. We believe that by excluding these charges, we provide our investors with supplemental information that is useful in comparing our operating results from period to period and in evaluating our core operations and performance.
(e)	This adjustment represents the income tax effects of the reconciling items noted in footnotes (a), (b), (c) and (d) as well as changes in the valuation allowance relating to the company’s deferred tax assets.
(f)	This adjustment represents the effects of the reconciling items noted in footnotes (a), (b), (c), (d) and (e).
(g)	This adjustment represents the effects of the reconciling items noted in footnotes (a), (b), (c), (d) and (e), on a diluted per share basis.
(h)	This reconciling item for the non-GAAP diluted earnings per share calculation includes the impact of our convertible senior notes as these were anti-dilutive for the equivalent GAAP earnings per share calculations.
