The Anritsu 68347B is a synthesized sweep/signal generator delivering phase-locked RF signals from 0.01 to 20 GHz. It generates discrete CW frequencies, performs broad and narrow band sweeps, and supports analog, step, and manual sweep modes with output power ranging from –125 dBm to +17 dBm. The instrument provides ultra-low SSB phase noise of –100 dBc at 10 kHz offset from 10 GHz, enabling precision testing of receivers, mixers, and RF components in laboratory and production environments.
