What happened to IFR ???   In 2002 Aeroflex Inc. (a New York-based holding company) bought IFR for about $60 million and folded it into their other holdings as "Aeroflex Test Solutions".

Note that there is no actual unit called the (whatever model-number)S/A, it's an abbreviation. The one manual would be for both the S-model and the A-model. The A-model does not have the spectrum analyzer and tracking generator options, the S-model does. And in response to several emails, no, I don't know if an A-model can be field converted into an S-model, or where to get parts, or how to do it.

A lot of older IFRs use blue fiberglass circuit boards. These boards are VERY fragile. You must do ANY necessary soldering with great care and quickly to avoid overheating the board. Also, may old IFRs are having power supply problems. If anyone would like to do an article on troubleshooting and repair we'd be happy to put it here. Likewise an article on attenuator repair, oscilloscope tube replacement, or on any other IFR-related topic.

Most of the IFR products used the same option list:

One of the companies that services IFRs is KG electronics In Wichita Kansas. Contact Kurt Graber at 316-773-0948 or kurtgraber //at// yahoo //dot// com.


IFR made a lot more models that we have listed below. What's below is what we have.
If you don't see what you need here, then we weren't given it.
Donations of manual files for this page (and other pages at this web site) are gratefully accepted.

On some of the equipment below we couldn't get the real IFR docs but were given the military docs. Note that the AN/GRM-114 is the military designation for the IFR 1000S and AN/GRM-114A is a different piece of equiment - the 1100S. Note that some are TM Technical Manuals and others are TB Technical Bulletins.
