The HP/Agilent 83620A Synthesized Sweeper is a signal generation instrument covering 10 MHz to 20 GHz, designed for RF and microwave component, device, and system testing. It combines synthesizer, sweeper, and modulation functions in a single unit. The instrument delivers precise frequency control through indirect synthesis with 1 kHz standard resolution (1 Hz optional), maximum leveled RF output of +13 dBm, and phase noise of −70 dBc at 20 GHz with 10 kHz offset. Harmonics are suppressed to at least 50 dB below the carrier from 2.0 to 20 GHz.
