Agilent / Keysight E4437B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E4437B. 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 E4437B 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.
