The Anritsu 68085B is a synthesized continuous wave (CW) generator engineered for high-precision signal generation across microwave and millimeter-wave frequencies. Operating from 0.5 GHz to 60.0 GHz, it delivers ultra-low single sideband phase noise of –100 dBc at 10 kHz offset from 10 GHz and output power ranging from –125 dBm to +17 dBm. The instrument combines frequency stability with flexible modulation and sweep capabilities, making it suitable for component characterization, system validation, and manufacturing test environments.
