Fluke 9500B Oscilloscope Calibrator Repair
The Fluke 9500B is an oscilloscope calibrator – it generates the fast edges, levelled sine waves and precise time marks that oscilloscopes are verified against. The specifications it must hold are unusual: edge rise time and amplitude flatness across bandwidth, which depend on output circuitry very different from a general-purpose calibrator.
June Company’s certified technicians repair the Fluke 9500B for calibration laboratories, oscilloscope service centres, and metrology departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke 9500B problems we fix
- Levelled sine amplitude flatness out of tolerance.
- Time-mark accuracy drift.
- Output or measurement drifted out of tolerance – corrected and verified against reference standards.
- Output connector or head faults.
- Communication or data transfer failures – which breaks automated procedures while the instrument still works manually.
- Display, keypad or interface faults.
- Fast-edge output degraded – rise time no longer meeting specification, which quietly invalidates every bandwidth verification performed with it.
FAQs
How long does a repair take? Most are completed in 5-10 business days, with a firm quote after evaluation and before any work starts.
How is edge performance confirmed after repair? Against reference standards, with the measured results documented – a scope calibrator whose edge has degraded will still produce a signal, just not a valid one.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
