Keysight 6811C AC Power Source Repair
The Keysight 6811C is a programmable AC power source/analyzer — it generates clean, programmable AC voltage and frequency with built-in measurement and analysis (including transients and harmonics), for testing products against varying line conditions. As an AC-generation instrument, its faults concentrate in the output amplifier stage, waveform/regulation circuitry, and the measurement system.
June Company repairs and calibrates the Keysight 6811C for product-test, avionics, and production teams.
Common Keysight 6811C problems we fix
- No output or won’t reach setpoint — AC output-amplifier failure, repaired so it sources full programmed voltage and current.
- Waveform distorted or frequency off — waveform-generation or regulation degradation, recalibrated for clean AC.
- Measurement / analysis off — the built-in metering and analysis drifting, recalibrated against standards.
- Won’t program or communicate — remote-interface faults, restored.
- Fan or protection-shutdown faults.
FAQs
My 6811C output is distorted — fixable? Yes. Output-amplifier and waveform faults are repairable, then verified so it delivers clean AC at the programmed voltage and frequency, with a NIST-traceable certificate.
Is the measurement verified? Yes — the metering and analysis are recalibrated against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
