The Anritsu 68165B is a microprocessor-controlled synthesized sweep generator delivering precision microwave signal generation across 0.5 to 40.0 GHz. It produces discrete CW frequencies and full-range or narrow-band sweeps with both analog and step-sweep capability, supporting dwell times from 1 ms to 99 seconds and switching times below 15 ms + 1 ms/GHz. The instrument integrates AM, FM, phase modulation, and pulse modulation—including doublet, triplet, and quadruplet pulse modes for radar testing—with seven internal waveforms plus user-defined arbitrary waveforms. Simultaneous synchronized modulations handle complex signal scenarios. Phase noise reaches –100 dBc at 10 kHz offset from 10 GHz. Output reaches +17 dBm. Front-panel or GPIB/IEEE-488 remote control enables local operation or integration into automated test systems. Step agility supports up to 1,000 non-sequential stored frequencies, and the optional AM SCAN modulator provides 60 dB modulation depth.
