Description
Fluke 96270A Reference Source Repair
The Fluke 96270A is a low-phase-noise RF reference source — a metrology-grade signal source (to ~27 GHz) that generates precise leveled RF and microwave signals, with optional noise/AM-FM capability, to calibrate level and frequency in 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 96270A for RF/microwave calibration labs.
Common Fluke 96270A problems we fix
- Relay / output-switching failures — the level-setting or path switching not working, repaired.
- Output-level / leveling drift — the RF level drifting so it’s no longer a trustworthy reference, recalibrated against standards.
- Frequency / synthesizer faults — source drift or unlock, repaired.
- Modulation faults — AM/FM/noise functions not working, restored.
- Communication or display faults.
FAQs
My 96270A level or switching is faulty — fixable? Yes. Switching, leveling, and reference faults are repairable, then the source is recalibrated so the analyzers and receivers 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.
