The HP/Agilent 83651A is a synthesized sweeper that generates RF signals from 45 MHz to 50 GHz with 1 Hz frequency resolution. This instrument serves as a dedicated source for Agilent 8510 systems, delivering precise signal generation for microwave component and subsystem characterization. Frequency accuracy in CW mode tracks the internal time base; in swept mode, accuracy reaches 0.1% of sweep width plus time base error for frequencies up to 26.5 GHz and sweep widths to n × 10 MHz. The rear-panel RF output provides 10 dBm maximum power.
