Hi Firas.Lachhab,
Since this driver is not supported by National Instruments, we do not have much information on the possible errors. I would recommend that you can visualize the proper way to configure the first VI. Also, you can try to verify downloading and installing again the IVI Driver from the following link:
This is because the error says that the Attribute is not found. Verify compatibility and all require information on the Rohde-schwardz web page as well.

Hi Firas.Lachhab,
you are using 3 different instrument drivers:
rscmwgg
rscmwgs
rscmwgm
You can't use the same VISA session for them. You have to initialize 3 different sessions with:
rscmwgg Initialize.vi
rscmwgs Initialize.vi
rscmwgm Initialize.vi
and the use them separately.

Hi,
I am developping a code for GSM test using R&S CMW500, but i have serious problem in some functions like:
-Packet Switched UL Slot (using the default parameters)
-Packet Switched DL Slot (using the default parameters)
-MultiEval Measurements list mode ALL state (using the default parameters)
-Phase error Limits (using the default parameters)
-Fetch Multi Eval list Mode All phase error results (using the default parameters)
and It returns a varant errors like:
-Command protected
- error parameter state....
the only result that t succeeded to get it some times is the Phase error, the problem is that the program enter in mode run state but it doesn't show any results, and when i leave the remote mode, the run state work normaly (manually).
NB: when I run the test manually from CMW500, in the run case, i see a red circle that is writen (Underdriven and when I consult the help of Labview i find this explication: rscmwgm Read Multi Eval Phase Error Trace <script src="/t5/forums/replypage/board-id/170/message-id/pdf.js" type="text/javascript"></script> <script src="/t5/forums/replypage/board-id/170/message-id/web.js" type="text/javascript"></script> <script src="/t5/forums/replypage/board-id/170/message-id/nonscroll.js" type="text/javascript"></script>
Underdriven: Measurement values available, however, the accuracy of some results may be impaired because the input signal level was too low |
but i don't Know how to solve it.
Many Thanks.
Best Regards,

Hi Firas.Lachhab,
I would recommend asking the people of Rohde-Schwarz, because they are the ones that support this driver and may have the documentation about errors.
