Rohde & Schwarz CMU200
_Wim_:
For measuring the frequency responce, you also can use the FreRes software (https://www.rohde-schwarz.com/uk/applications/freres-program-for-frequency-response-measurements-application-note_56280-15551.html) where the generator and analyser are configured for as many frequency points as you want. You can get a very high resolution read-out, but that takes a long time. But still, very usefull.

i love my cmu200, the only downsides are no preamplifier option, and it only goes down to 10mhz.
it has a great signal generator, and with freeres i even have a poor man's tracking generator.
for what i paid for it, it's a phenomenal value.

I'm rather keen on mine too, I've been tinkering with using one of the RF generator outputs as a LO for an external ADE-1 mixer, yet to quantify results but it seems to work.
I am having problems getting results from FreeRes though, I'd be grateful for any tips on configuration of the CMU and PC?
Brainbox:
I have both the tracking generator and the noise generator.
From those I prefer the tracking generator for its broader band.
The noise generator only have a satisfaction output in a small band.
Higher the bandwidth decrease the output level ans also the resolution.
But it can be useful for preselection purpose.
FreRes also is a great solution but requires the use of a external PC.

Hi,
I'm looking into buying a CMU200. But I'd like to know a few things.
Can the built in generator do FM, AM, or any other analog modulation types?
Can any of the analog modulation types be analyzed/demodulates?
I tried to find general info on the CMU200, but I could only find documentation on for example how to do GSM measurements.
No general manual or any other information.
Thanks,
Michael
