Hi,
I'm working on getting spectrum data from R&S spectrum analyzer CMU 200.Well I'm totally new in this domain cauz actually i just want to acquire signal from the spetrum and save it as csv file for example to work on optimization with genetic algorithm.I have RSCommander program on pc I get connected with the spectrum through GPIB connection but the problem here is that 'trace' in disabled as well as 'hardcopy' I tried something else I donwlaoded the prgram FSxRecordPlay but I get the error 'check for connection and make sure you have the right instrument descriptor'.I'm blocked since a month because every day I try something new and dosen't work with me I'm so confused.
Please is there any solution or another method I can follow.
Thank you.
Solved! Go to Solution.

Hello zaynebzayneb,
Can you tell me more about the National Instruments's product you are using?
Thank you and have a good day!

Hello I'm using National Instrument GPIB_USB adaaptor to get connection pc/spectrum analyzer

Hi zaynebzayneb, RSCommander does not support CMU200 as a spectrum analyzer - therefore reading the trace does not work.

ok thank you you confirm my doubt. So is there any solution or other method you can propose for me?

Which programming environment are you skilled in?
06-11-2018 04:20 AM
Well eclipse IDE.Or I'm thinking of matlab but concerning matlab I don't know several functions but if there is a practical solution I'm ready to work on it .

Matlab is a good tool for such tasks, I wrote an Application Note 1MA171 on the topic of remote-controling instruments from Matlab: http://www.rohde-schwarz.com/appnote/1MA171
But you need to get familiar with the SCPI commands language - I suggest a small tutorial here:
https://www.rohde-schwarz.com/driver-pages/remote-control/drivers-remote-control_110753.html
Go through the 1MA171 Chapter 2: Direct SCPI Commands Communication and try the MATLAB_directSCPI_Hello_World.m example. Let me know if you've managed to connect to your instrument.
Cheers

okk I will read the tutorial and try to run the example. I will inform you if I managed to connect it or not.
thank you

Hello I tried Hello world example but it doese not work cauz it is GPIB connection and not TCPIP so I tried the Instrument control toolbox and it work with me but the problem here is that I try to customize the code to work with me but for example the property '.Write' is not an accessible property for VISA_GPIB. What I can do in this case
