This unit
The HP/Agilent 83640B is a synthesized swept-signal generator delivering precision frequency synthesis across 0.01 GHz to 40 GHz with +10 dBm calibrated output power. Built on indirect synthesis architecture, this instrument achieves superior single-sideband phase noise performance while maintaining broad spectral coverage. The 83640B supports multiple operational modes
CW, step sweep, list mode, manual sweep, ramp sweep, and analog sweep variants - alongside modulation capabilities including pulse, AM, and FM. Frequency resolution reaches 1 Hz with Option 008, stepping down to 1 kHz standard. Output power ranges from -20 dBm to +10 dBm leveled; Option 001 extends the range to -110 dBm minimum. Switching time of 10 ms typical (without attenuator change) enables rapid frequency transitions. Temperature stability holds 0.01 dB/°C for output power. This generator is engineered for radar system characterization, wireless communication testing, and microwave circuit validation where signal purity and dynamic range matter.

HP / Agilent 83640B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 83640B. 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 83640B 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.
