The Anritsu 37369A is a microprocessor-controlled vector network analyzer spanning 40 MHz to 40 GHz in a single, compact bench-top instrument. It integrates a synthesized signal source, S-parameter test set, and four-channel receiver into one system for high-frequency characterization of RF and microwave components, networks, and systems. The instrument delivers fast measurement throughput with sub-3 ms update rates per point and supports extensive analysis modes including S-parameters, amplitude and phase tracking, group delay, time domain analysis, and filter nonlinear response identification.
