I know from personal
experience that, at least a few years ago, both
Agilent in Loveland, CO, and Narda in Happauge,
NY, had equipment to make PIM measurements.
Agilent used equipment designed and
manufactured by Summitek in Colorado (http://www.summitekinstruments.com/
had a custom in-house setup.
I do not
have names for contacting either company, but
you could just try calling the main phone
numbers and ask. You might also try contacting
Summitek to see if they can either do the
testing or recommend a test facility.
