These capabilities allow spectrum analyzers to provide frequency- domain signal analysis for numerous applications, including the manufacture and maintenance of microwave communication links, radar, telecom equipment, CATV systems, and broadcast equipment ; EMI diagnostic testing ; and signal surveillance.
( I can't believe they actually said that. Gee, I wonder if They're going to classify test & measurement equipment next. )-: We use them all the time to track down pirate stations and wierd emissions (spurs, harmonics...). BTW... If you have an O-Scope that has X-Y inputs, it isn't that difficult to design and build a low-end, front-end for the scope that will provide the same functions as a spectrum analyzer.
I'm not encouraging you to spoof these folks, merely noting that it is a regrettable necessity. If you don't present yourself as a prospect, they may blow you off, and if you give any hint that you don't represent some sort of company, you are sure to be blown off, presumed to be a waste of their time. ( Of course, this posting may lead to three or four analyzers, $ 100-200 thousand worth of sales, but try to persuade a salescritter of this. :-)
I think they partially do this 'cause the catalogs are so bloody expensive to produce. They are an education if you get one. Tim -- Internet: pozar@kumr.lns.com FidoNet: Tim Pozar @ 1:125/555 Snail: Tim Pozar / KKSF / 77 Maiden Lane / San Francisco CA 94108 / USA Voice: +1 415 788 2022
