The Agilent/Keysight N9340A is a portable handheld RF spectrum analyzer built for field signal analysis, interference detection, and antenna/cable testing from 9 kHz to 3 GHz. Its 7.2-inch sunlight-viewable display and four-hour battery life enable extended field campaigns in demanding environments. The instrument delivers –124 dBm displayed average noise level (DANL) at baseline, extending to –144 dBm with the optional 3 GHz preamplifier in the 10 MHz to 1.5 GHz band, supporting detection of weak signals across multiple applications.
