Anritsu MS4622B

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.

Technical Specifications Frequency Range: 10 MHz to 3 GHz Dynamic Range: 125 dB Measurement Speed: 150 ms/point; 150 µsec/point Port Configuration: 2-port standard; 3-port and 4-port configurations available with optional modules.
