Description
Fluke 96040A Reference Source Repair
The Fluke 96040A is an RF reference source — a metrology-grade signal source that generates precise, low-level leveled RF signals (to ~4 GHz) to calibrate RF level in measuring receivers, spectrum analyzers, and related instruments. Its faults concentrate in the RF output and leveling, the internal reference, and the attenuator/output switching.
FlukeMeterRepair.com repairs and calibrates the Fluke 96040A for RF calibration labs.
Common Fluke 96040A problems we fix
- Automated-calibration / artifact faults — the automated or artifact-cal routines not running correctly, repaired.
- Output-level / leveling drift — the RF level drifting so it’s no longer a trustworthy reference, recalibrated against standards.
- Attenuator / output-switching faults — the level-setting switching not working, repaired.
- Frequency / synthesizer faults — source drift or unlock, repaired.
- Communication or display faults.
FAQs
My 96040A output level is off — fixable? Yes. Leveling, attenuator, and reference faults are repairable, then the source is recalibrated so the receivers and analyzers you calibrate are trustworthy, with a NIST-traceable certificate.
Is the level verified? Yes — RF level and frequency are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
