This unit
The HP/Agilent 83651A is a synthesized sweeper that generates RF signals from 45 MHz to 50 GHz with 1 Hz frequency resolution. This instrument is a dedicated source for Agilent 8510 systems, delivering precise signal generation for microwave component and subsystem characterization. Frequency accuracy in CW mode tracks the internal time base; in swept mode, accuracy reaches 0.1% of sweep width plus time base error for frequencies up to 26.5 GHz and sweep widths to n × 10 MHz.
The rear-panel RF output provides 10 dBm maximum power.

Compatibility & Integration The 83651A is optimized as a dedicated source for Agilent 8510 systems. Rack mounting options include slide kits (806), flange kits with handles (913), and flange kits without handles (908). Military standard calibration certifications (45662A) with or without test data are available. Commercial calibration with test results data is also offered.
HP / Agilent 83651A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 83651A. 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 83651A 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.

HP / Agilent 83651A calibration cost
NIST-traceable calibration for the HP / Agilent 83651A is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument 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. Turnaround is 1 to 3 business days after receipt. See full calibration details →
