Does anyone know the differences between a CMU200 and a CMU300 by heart? Looking through the specs and manuals they seem identical.

Thanks,
Michael

There are indeed some significant differences. As the CMU-300 is for testing the GSM BTS, it has one RF input that's capable of accepting a full 50W RF power. Mind you, when you stick in above 30W it does start to get a bit smelly!

It has a nice spectrum analyser (up to 2GHz as I recall) and also a signal generator with some modulation options. You can use these combined to test RF components, amplifiers, cables etc.

I would challenge anyone to come up with a spectrum analyser with a 50W input - calibrated.

Without the additional RF Generator (i think its option B96) the normal CMU200 can also take 50W.

I just picked up a R&S CMU200 and it has B96, but I would rather have 50W input.  Can I remove the B96 option and restore the 50W input power handling?

As far as I know, the front end is different (including a fan to cool the input) so perhaps you can swap out the front end but its not like you can uninstall an option or something ;)

Thanks for the response.  Not what I wanted to hear, but an answer I can live with.

Next question: can I use a PCMCIA SD Card reader to load new software?  I see most people using PCMCIA CF readers.  Just wanted to know if I would run into trouble using a SD reader instead.
