The ICX-FieldHawk handheld real-time spectrum analyzer covers 9 kHz to 40 GHz with 100 MHz of real-time bandwidth, so brief and intermittent signals stay in view. The displayed average noise level is -159.9 dBm/Hz at 1 GHz. The 3.3 lb unit runs from a large 10.1-inch multi-touch display and supports IQ streaming, automatic phase noise analysis and SCPI remote control. Field teams use it for interference hunting, satellite ground station commissioning and 5G coverage testing.
