The Anritsu 37369D is a two-port Vector Network Analyzer delivering precise S-parameter characterization of active and passive devices from 40 MHz to 40 GHz. Built as part of the Lightning D series, this benchtop instrument integrates a synthesized source, S-parameter test set, and tuned receiver in a single chassis, serving defense, satellite, radar, broadband communication, and optoelectronic applications. Direct access to receiver samplers enables specialized measurement configurations without external controllers.
