The Keysight N9000A (formerly Agilent) is a versatile CXA Signal Analyzer and part of the X-Series portfolio. Designed as an economical, general-purpose spectrum analyzer, it delivers dependable fundamental signal characterization from 9 kHz up to 26.5 GHz depending on the installed option. It provides standard 10 MHz analysis bandwidth (expandable to 25 MHz) and built-in tracking generator capabilities for component testing. Running on an integrated Windows-based OS, the N9000A offers LXI Class C compliance, an 8.4-inch high-resolution color display, and wide compatibility with X-Series measurement applications.
