The Anritsu MS4622B is a 2-port vector network analyzer from the Scorpion series designed for RF and microwave component characterization in manufacturing and research environments. It delivers S-parameter measurements across 10 MHz to 3 GHz with 125 dB dynamic range, alongside advanced options including noise figure, intermodulation distortion, harmonics, and time domain analysis. A single connection to the device under test enables comprehensive passive and active component evaluation—antennas, filters, amplifiers, and mixers—with measurement speeds of 150 ms/point or 150 µsec/point depending on application.
