Description
Keysight E8663D Signal Generator Repair
The Keysight E8663D is an analog signal generator (PSG-series, to ~9 GHz) — it produces high-purity, low-phase-noise CW and analog-modulated signals for testing receivers, components, and systems. As a precision RF source, its faults concentrate in the synthesizer, the output leveling and attenuator, and the output stage.
June Company repairs and calibrates the Keysight E8663D for RF/microwave engineering and test teams.
Common Keysight E8663D problems we fix
- Output-level accuracy drift — the leveling loop/attenuator drifting so output level is wrong, repaired and recalibrated against standards.
- Frequency / phase-lock faults — synthesizer drift or unlock, recalibrated.
- No output — output-stage failure, repaired.
- Modulation faults — AM/FM/pulse modulation not working, restored.
- Display or interface faults.
FAQs
My E8663D output level is off — fixable? Yes. Leveling and synthesizer faults are repairable, then the generator is recalibrated so frequency and level accuracy are restored, with a NIST-traceable certificate.
Is the output level verified? Yes — level and frequency are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
