PSG-A Signal Generator RF Signal Generator 20 GHz High Power Agilent E8251A

A pre-owned Agilent E8251A combines 0.01 Hz synthesized accuracy with up to +20 dBm output across 250 kHz -20 GHz, giving R&D and production benches a single-box source for low-noise local oscillators, PA compression, receiver sensitivity and EMC immunity work. Typical phase noise of -110 dBc/Hz keeps mixers honest, while the 110 dB electronic step attenuator (Opt 1E1) delivers a calibrated -110 dBm floor without external pads. Built-in AM/FM/PM plus digital list and step sweeps speed device characterisation, and SCPI/LAN control drops straight into automated test code.

Refurbished units ship ISO-17025-calibrated with current firmware, trimming capital cost and lead-time yet preserving Keysight reliability and future option paths.
