Anritsu 69065A Synthesized CW Generator

The Anritsu 69065A is a synthesized CW generator delivering stable, phase-locked signal output across 0.5 GHz to 40 GHz for microwave test and measurement applications. This instrument generates discrete CW frequencies with ultra-low single-sideband phase noise of -100 dBc at 10 kHz offset from a 10 GHz carrier, making it ideal for demanding component analysis and signal simulation tasks.
