This unit
The Keysight (Agilent) 83631B is a synthesized signal source engineered for precision RF testing and system integration. Operating from 45 MHz to 26.5 GHz with 1 Hz frequency resolution, it delivers stable, repeatable signal generation across microwave and millimeter-wave bands. The instrument features rear-panel output connectivity and operates without front-panel controls, positioning it as a dedicated component within automated test systems.
Output power ranges from −20 dBm to +10 dBm, with maximum leveled output of +13 dBm below 20 GHz and +10 dBm at frequencies up to 26.5 GHz.

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