Description

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.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
