Fluke 9640A RF Reference Source Repair

The Fluke 9640A is an RF reference source — a metrology-grade leveled sine source (to ~4 GHz) used in cal labs to calibrate RF level meters, attenuators, and the RF functions of other instruments with precise, accurately-leveled output. As a precision RF source, its faults concentrate in the synthesizer/reference, the leveling loop and output stage, and the output connector.

June Company repairs and calibrates the Fluke 9640A for calibration labs and metrology teams.

Common Fluke 9640A problems we fix

Output-level / leveling faults — the leveled output drifting or not meeting spec, which compromises RF cals, recalibrated against standards.
Frequency accuracy / lock faults — synthesizer drift or unlock, repaired.
Low or no output — output-stage failure, repaired.
Output-connector faults — the precision RF output, serviced.
Interface or control faults.

FAQs

My 9640A output level drifted — fixable? Yes. Leveling and output-stage faults are repairable, then the source is recalibrated so its leveled RF output is accurate and your RF cals are trustworthy, with a NIST-traceable certificate.

Is the leveling verified? Yes — level and frequency accuracy are 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.
