Accounting Policies [Abstract]
OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. OVERVIEW 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 development 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 January 31, 2023 and October 31, 2022, results of operations for the three months ended January 31, 2023 and 2022, and cash flows for the three months ended January 31, 2023 and 2022. 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. Update to Significant Accounting Policies. Except as set forth in the "new accounting pronouncements" section below, 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, 2022. Reclassifications. Beginning in fiscal year 2023, to align the presentation of revenue with the manner in which management reviews such information, the presentation of "products" and "services and other" revenue and the presentation of "costs and expenses" in the condensed consolidated statement of operations were reclassified to move revenue and costs and expenses primarily related to bundled licenses and KeysightCare services from products to services and other. This resulted in reclassification of $20 million from "products" revenue to "services and other" revenue and $3 million from "cost of products" to "cost of services and other" for the three months ended January 31, 2022 to conform to the current presentation. This change had no impact on reported total revenue, income from operations and net income in our condensed consolidated statement of operations. New Accounting Pronouncements. Other amendments to GAAP that do not require adoption until a future date are not expected to have a material impact on our condensed consolidated financial statements upon adoption.
