The Advantest R3182 is a 9 kHz to 40 GHz spectrum analyzer engineered for signal analysis across communications, research, manufacturing, and maintenance applications. It delivers frequency, amplitude, and modulation characterization with an average display noise level of -106 dBm/RBW 1 kHz at 40 GHz and SSB phase noise of -85 dBc/Hz at 40 GHz (20 kHz offset). The instrument spans a dynamic range of +30 dBm to -132 dBm with ±1.5 dB overall level accuracy from 100 kHz to 3 GHz after calibration.
