Frequently Asked Questions
How much does Keysight FieldFox repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most FieldFox repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My test port connectors are worn or readings jump when I move the cables — can you fix it?
Yes. N-type and 3.5mm test port connector wear from repeated field connections is one of the most common FieldFox repairs, restored for stable, repeatable measurements.
My battery won’t hold a charge — is that repairable?
Yes. Battery cell degradation from charge cycling is routine on field instruments and fully repairable, restored for reliable runtime away from power.
My readings are drifting or out of spec — can you recalibrate it?
Yes. We recalibrate across the instrument’s measurement modes against our reference standards and return it with NIST-traceable results on a certificate.
The display is cracked or dead after a drop — can you replace it?
Yes. LCD failure from field impact or temperature extremes is a common FieldFox repair, and the display is fully replaceable.
It won’t lock or the GPS won’t acquire — is that repairable?
Yes. Internal synthesizer lock failures and GPS module faults are both repairable at the component level, restored to proper operation.
What if my exact model isn’t listed?
We service every FieldFox configuration across the A and B series. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the Keysight FieldFox?
Cell tower installation and maintenance crews, satellite ground station technicians, military RF maintenance teams, broadcast engineers, cable/antenna installers, and field RF troubleshooters rely on the FieldFox as a single rugged, multi-function field instrument.
