Keysight N9322C Basic Spectrum Analyzer, 9 kHz to 7 GHz

The Keysight N9322C Basic Spectrum Analyzer is a general-purpose instrument for spectrum analysis and signal monitoring from 9 kHz to 7 GHz. It delivers absolute amplitude accuracy of ±0.3 dB and outstanding noise performance with a displayed average noise level of -152 dBm at 1 GHz (10 Hz minimum RBW). The instrument features a 50 dB input attenuator with 1 dB steps, adjustable resolution bandwidth from 10 Hz to 3 MHz, and a maximum analysis bandwidth of 1 MHz.

Phase noise performance reaches -115 dBc/Hz at 1 MHz offset and -90 dBc/Hz at 10 kHz offset. Sweep times range from 2 ms to 1000 s for spans ≥100 Hz, with frequency stability rated at ±0.1 ppm annual aging.
