Keysight (Agilent) N9342C Handheld Spectrum Analyzer (HSA), 7 GHz

The Keysight N9342C Handheld Spectrum Analyzer delivers benchtop-class RF signal analysis in a field-deployable package. Operating from 100 kHz to 7 GHz with tuning capability down to 9 kHz, this rugged analyzer combines high sensitivity (-152 dBm DANL) with fast sweep performance (< 0.4 seconds full span) for demanding field environments. MIL-PRF-28800 Class 2 compliant construction, weather-resistant design, and a fanless architecture ensure reliable operation across -10 °C to +50 °C without sacrificing portability at 3.2 kg.
