The Advantest R3162 is a 9 kHz to 8 GHz spectrum analyzer engineered for RF and microwave characterization across development, production, and service environments. Built on direct digital synthesis architecture, it delivers 1% frequency span accuracy and maintains a 117 dB dynamic range through exceptional distortion performance: -80 dBc second-order harmonic distortion, -80 dBc two-signal third-order intermodulation distortion, and a 0 dBm input 1 dB gain compression point.
