The Keysight N9320BK is a compact RF spectrum analyzer spanning 9 kHz to 3 GHz, delivering precise signal analysis across monitoring, component testing, and EMC pre-compliance applications. With a displayed average noise level of −148 dBm (preamplifier enabled), 1 Hz resolution bandwidth, and ±0.5 dB amplitude accuracy, it provides laboratory-grade measurement performance in a portable form factor. The instrument features an internal 10 MHz frequency reference with ±1 ppm/year aging stability and supports optional GPIB connectivity for automated test environments.
