The Anritsu 68353B is a synthesized sweep/signal generator delivering precision RF signal generation across 2 to 26.5 GHz for high-frequency system testing. Built for radar, satellite, and advanced RF applications, it combines ultra-low phase noise (–100 dBc at 10 kHz offset from 10 GHz) with flexible modulation and rapid frequency switching to meet demanding measurement requirements.
