The pre-owned Agilent 83651B delivers fully synthesized accuracy and analog-sweep convenience from 2 GHz up to 50 GHz in a single 3-U chassis. One-kilohertz tuning—down to 1 Hz with the fractional-N option—makes it a crystal-clean local oscillator, while a typical –80 dBc/Hz phase-noise floor keeps mixer and phase-noise measurements honest. With the optional 110 dB electronic step attenuator, the source spans +10 dBm to –110 dBm, covering PA compression, receiver sensitivity, and EMC tasks without external pads.

Fast band switching, list sweeps, and SCPI/LAN automation let the generator drop straight into automated R&D or production benches, providing Keysight-grade signal purity and long-term serviceability at a fraction of new-unit cost.
