The HP/Agilent 83752B High Power Synthesized Sweeper generates RF and microwave signals across 0.01 GHz to 20 GHz with synthesized frequency accuracy and multiple sweep modes. Designed for component characterization, system validation, and benchtop measurement, it delivers maximum leveled output of 17 dBm above 2 GHz and 16 dBm below 2 GHz. The instrument supports fully synthesized CW, stepped, and ramp sweep modes with 1 Hz frequency resolution, external AM/FM modulation, and internal pulse generation.
