Status: 5790B / 9640A Current Production — 5790A / 96040A / 96270A Legacy
Overview
Fluke measurement standards and RF reference sources serve as the accuracy foundation in primary and secondary calibration laboratories. The 5790A/B AC Measurement Standards provide the highest accuracy AC voltage measurements for verifying multifunction calibrators. The 9640A and legacy 96040A/96270A RF Reference Sources provide traceable power and attenuation standards for RF and microwave calibration.

Common Fluke Measurement Standards Failures We Repair
- AC thermal converter drift requiring recalibration against primary standards
- RF output leveling loop degradation at high frequencies
- Internal reference standard long-term drift beyond specified tolerance
- Precision attenuator calibration shift from mechanical wear
- GPIB communication failures in automated lab environments
Our technicians perform component-level diagnostics on every Fluke Measurement Standards unit. We don’t just replace boards — we identify and repair the specific failed components, saving you the cost of full module replacements when possible.
Calibration
Every Fluke Measurement Standards repair includes NIST-traceable calibration. We verify all primary output and measurement functions against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.
Who Uses the Fluke Measurement Standards?
The Fluke 5790A/B AC Standards and 96xxA RF Reference Sources are used by national metrology institutes, primary standards laboratories, RF calibration facilities, military electronics calibration, and calibrator verification programs.
