Advantest R3371 – Spectrum Analyzer 100 Hz – 26.5 GHz max portable

The Advantest R3371 is a portable spectrum analyzer spanning 100 Hz to 26.5 GHz, engineered for signal analysis, component testing, and electromagnetic compatibility (EMC) evaluation. This instrument delivers 110 dB dynamic measurement range with tracking generator, 120 dB display dynamic range, and ±1 dB total level accuracy. The built-in tracking generator operates from 100 kHz to 3.6 GHz with output levels from -3 dBm to -30 dBm and ±0.5 dB accuracy at 25 MHz reference conditions. Phase noise performance reaches -110 dBc/Hz at 10 kHz offset below 2.6 GHz.
