The Anritsu 69397A is a synthesized sweep/signal generator delivering precise, stable RF signal generation across 0.01 to 65 GHz. Purpose-built for local oscillator replacement and demanding CW applications, this instrument combines ultra-low SSB phase noise at -107 dBc/Hz (10 kHz offset from 10 GHz) with flexible sweep architectures and comprehensive modulation capability. Output spans -125 dBm to +17 dBm with optional 0.1 Hz frequency resolution.
