This unit
The Agilent/Keysight 8660D is a modular, solid-state synthesized signal generator mainframe that is the foundation for precision RF and modulation applications. It accepts plug-in RF and modulation modules to establish frequency coverage, output level, and modulation capability tailored to specific test requirements. The mainframe itself provides the synthesizer core, display, control logic, and interface infrastructure; actual signal generation depends on installed RF plug-in sections.
Technical Specifications

Agilent / Keysight 8660D — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8660D. 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 8660D 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.
