This unit
The HP/Agilent 83631A is a synthesized signal source engineered for precise microwave signal generation across 45 MHz to 26.5 GHz. Purpose-built for integration with Agilent 8510 network analyzer systems, this instrument combines the stability of a synthesized source with sweep oscillator versatility. It delivers 1 Hz frequency resolution and operates without modulation capabilities or front-panel controls - all configuration and output management occurs via rear-panel connections and programming interfaces.
Technical Specifications

HP / Agilent 83631A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 83631A. 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 HP / Agilent 83631A 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.
