The Anritsu 37347C is a Vector Network Analyzer operating from 10 MHz to 20 GHz, designed for precise S-parameter characterization of passive and active RF and microwave components. It delivers full two-port S-parameter measurement capability (S11, S12, S21, S22) with dynamic range reaching 110 dB at 10 MHz and 100 dB at 20 GHz. The instrument supports frequency sweep, power sweep, group delay, and time-domain analysis across 1 to 401 data points per measurement.
