Anritsu 37317A Vector Network Analyzer (22.5 MHz to 8.6 GHz)

The Anritsu 37317A is a microprocessor-controlled Vector Network Analyzer for bench-top RF and microwave component characterization. Operating from 22.5 MHz to 8.6 GHz, it integrates a synthesized source, S-parameter test set, and tuned receiver into a single compact unit. The instrument supports S-parameter measurements (S11, S21, S22, S12) with flexible calibration methods including LRL, LRM, and Adapter Removal techniques.
