The Anritsu 68377C is a synthesized signal generator delivering precise RF and microwave stimulus across 10 MHz to 50 GHz for defense, satellite, and wireless communication test environments. The instrument combines ultra-low phase noise with accurate leveled output power down to −120 dBm in 0.01 dB steps, meeting stringent requirements for sensitive receiver characterization. Frequency switching completes in less than 5 ms, accelerating automated test sequences. Its compact 13.3 cm footprint minimizes rack real estate while supporting SCPI programmability with IVI-COM and LabVIEW driver compatibility for seamless ATE integration.
