This unit
The Keysight E8257D PSG Analog Signal Generator delivers signal synthesis across 250 kHz to 67 GHz, with operational capability to 70 GHz. Purpose-built for RF and microwave characterization, it combines exceptional phase noise, wide dynamic range, and precise frequency control to support radar, communications, and component testing. The instrument achieves 0.001 Hz frequency resolution in CW mode and maintains spectral purity through harmonic suppression to -55 dBc with optional filtering.

Agilent / Keysight E8257D — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8257D. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E8257D faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.
