Acquire signal data from Rohde and schwarz CMU200 / GPIB

[zaynebzayneb]

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.

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.

[zaynebzayneb]

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

[MM_RohdeSchwarz]

Which programming environment are you skilled in?

[zaynebzayneb]

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
