Description
Keysight 6812C AC Power Source Repair
The Keysight 6812C is a performance AC power source / analyzer — it generates clean, programmable AC voltage and frequency with built-in measurement and analysis, for testing products against varying line conditions. As an AC-generation instrument, its faults concentrate in the output amplifier stage, waveform/regulation circuitry, and measurement.
June Company repairs and calibrates the Keysight 6812C for product-test and production teams.
Common Keysight 6812C 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 at the set frequency.
- Measurement / analysis off — the built-in metering drifting, recalibrated against standards.
- Won’t program or communicate — remote-interface faults, restored.
- Fan or protection-shutdown faults.
FAQs
My 6812C output is distorted or measurement is off — fixable? Yes. Output-amplifier and measurement faults are repairable, then verified so it delivers clean AC at the programmed setpoint and measures accurately, with a NIST-traceable certificate.
Is the measurement verified? Yes — output and metering 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.
