Avionics Test Sets — Buy & Sell Used Avionics Test Sets

MROs, repair stations, and avionics shops rely on a short list of ramp test sets — and certified used units cost a fraction of new with the same capability after calibration. We buy retired sets from shops consolidating or closing, and sell with fresh cal certs whenever possible.

Avionics Test Sets Buying Guide

Avionics test sets are selected on the systems they test and the standards they cover. Ramp and bench sets address transponders and TCAS, navigation (VOR, ILS localizer/glideslope, marker beacon), DME, communications, ADS-B, ELT, and pitot-static — and few units cover all of them, so start by matching the set to the airframes and systems your shop services. For transponder and surveillance work in particular, confirm Mode S and ADS-B (DO-260B) capability, since that determines compliance with current airspace requirements.

Used value follows the installed test functions and options, but for avionics there's an overriding factor: calibration. Certified maintenance work requires test equipment in current, traceable calibration, so a set sold with a fresh certificate is worth markedly more and is immediately usable. Common platforms include VIAVI/Aeroflex/IFR ramp sets, Tel-Instrument (TIC), and Barfield, and options like ADS-B, TCAS, and datalink testing add value, as do antennas, couplers, and cables. List the test functions, options, and cal status when you request a quote.

Refurbished avionics test sets typically save 40-70% off list and, when in calibration, perform to spec just as a new unit does. Ramp test sets with current ADS-B/Mode S capability hold value especially well. Whether you're sourcing a unit or retiring one, send us the model, its functions, and its calibration status, and we'll quote within one business day.

Frequently Asked Questions

How much is my used avionics test set worth?

Value depends on the systems it tests, installed options (ADS-B, TCAS, datalink), included accessories, and — importantly — current, traceable calibration. Send us the model and details and we'll return a fair-market offer within one business day.

What systems does a given test set cover, and does it support ADS-B?

Coverage varies by model and options — transponder/TCAS, nav (VOR/ILS/DME), comm, ADS-B, ELT, and pitot-static are distinct capabilities. For surveillance work, confirm Mode S and ADS-B (DO-260B) support specifically.

Can test functions be added later?

On some platforms, functions like ADS-B or datalink are upgradeable options. Installed options raise both capability and resale value.

Do you sell sets with current calibration, and do you buy out-of-cal units?

We can arrange calibration on units we sell, and we buy avionics test sets as-is, including out-of-cal. Since certified work requires in-cal gear, note the cal status when you request a quote.

Why buy refurbished instead of new?

Refurbished test sets typically cost 40-70% less than new and, when in calibration, perform to spec. Every unit is tested and verified, and calibration can be arranged.

Don't see your model listed?

The test equipment catalog is massive. We trade, buy, and sell thousands of unlisted models from Keysight, Tektronix, Rohde & Schwarz, and other manufacturers. Tell us what you need and our sourcing team will find it.
