Fluke 5800A Oscilloscope Calibrator Repair
The Fluke 5800A is an oscilloscope calibrator — a metrology-grade source that generates precise voltage, fast edges, leveled sine, time markers, and other signals to calibrate oscilloscopes in a cal lab. As a precision multi-function source, its faults concentrate in the reference, the output stages (especially the fast-edge and leveled-sine paths), and the output relays/switching.
June Company repairs and calibrates the Fluke 5800A for calibration labs and metrology teams.
Common Fluke 5800A problems we fix
- Reference / output drift — the reference or output stages drifting, which compromises every scope cal, recalibrated against standards.
- Fast-edge or leveled-sine faults — the edge or leveled-sine output not meeting spec, repaired.
- A function dead — an output path failed, often after a miswire, repaired.
- Output-relay / switching faults — the output routing, restored.
- Communication or display faults.
FAQs
My 5800A output drifted — fixable? Yes. Reference and output-stage faults are repairable, then the calibrator is recalibrated so its outputs are accurate and your scope cals are trustworthy, with a NIST-traceable certificate.
Are the fast-edge and leveled-sine verified? Yes — 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.
