31 IFR 1200 problems and fixes. In this video we take a look inside the IRF 1200 Service monitor. We will address the low output issue from the T/R jack and have a look at the termination dummy load failure. Used to have one of those and learned on it while in school back in 1980 or so I have a IFR-1200 now with spectrum here is a link to the whole op and service, its 2 books in one. IFR 1200 Super S Restoration. In 2004 I picked up a IFR1200 Super S in a trade deal. This is the upgraded version of what might be the most popular communications service monitor ever made. (I'm not sure why though-the HP8920 was far more functional, and many orders of magnitude more accurate and capable.

IFR 1200 Super S RestorationIn 2004 I picked up a IFR1200 Super S in a trade deal. This is the upgraded version of what might be the most popular communications service monitor ever made. (I'm not sure why though--the HP8920 was far more functional, and many orders of magnitude more accurate and capable. They were also comparably priced. Go figure. --Well, back to my story...)
Ifr 1200 Super S Manual
The 'Super' S is a little more rare than the standard 1200 S. It included a spectrum analyzer, and sweet options like built in cable test, harmonics test and Bessel functions. They came out near the end of the 1200 product life, and they were pricey. This one had been owned by a paging company that I did some work for, and had been used strictly as an over the air monitor to observe signal quality. (Again, a terrible choice for such a task! But, I digress...)
