Status: 9500B Current Production — 5800A / 5820A Discontinued. We repair and calibrate all of them.
Common Fluke Oscilloscope Calibrator Problems We Fix
- Leveled sine output amplitude out of tolerance or drifting
- Fast-edge / rise-time output degraded
- No output or unstable output on one or more functions
- Attenuator switching faults / contact resistance
- Reference oscillator frequency drift
- Won’t power on or power-regulation faults under switching
- Won’t communicate over GPIB (automated cal sequences fail)

Frequently Asked Questions
How much does Fluke oscilloscope calibrator repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most 9500B, 5800A, and 5820A repairs are finished within 5–10 business days of arrival. Because these are reference calibrators, we can discuss expedited turnaround if your lab is down.
My calibrator’s output is out of tolerance — can you bring it back into spec?
Yes. Leveled-sine amplitude drift and fast-edge degradation are the most common faults on these units. We repair the cause and verify output against our reference standards across the frequency range.
Do you repair the fast-edge and time-marker outputs specifically?
Yes. We service the full output set these calibrators provide — leveled sine, rise/fall edges, and time markers — restoring and verifying each one individually.
Do you still repair the discontinued 5800A and 5820A?
Yes. These legacy oscilloscope calibrators are fully supported for repair and recalibration — still widely used in military and aerospace programs — even though they’re no longer in production.
Can you fix GPIB faults that break automated calibration?
Yes. Interface board failures that stop GPIB control are a common repair, restored so your automated MET/CAL scope-cal sequences run again.
Is the repair NIST-traceable, and do I get a certificate?
Yes. Every repair includes NIST-traceable calibration of the output functions, documented on a certificate against Fluke’s published specifications — essential for a calibration-lab reference instrument.
Who uses Fluke oscilloscope calibrators?
Calibration laboratories, military electronics maintenance, aerospace test facilities, and oscilloscope manufacturers rely on the 9500B, 5800A, and 5820A to calibrate scopes traceably.
