Error -1074001656 occurred at RSCMUBT_Init_BT_Sig.vi

This error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input.

You should really have posted back to the <A href="http://forums.ni.com/ni/board/message?board.id=170&message.id=203922#M203922">thread</A you had already started. And, as I mentioned there, the driver is downloaded from R&S and it has been written by them. Since that error code is undefined and the LabVIEW driver is really a CVI driver, you have no LabVIEW source code to look at. My only suggestion is to contact R&S to see if someone there can explain the error. Can you get any functions in the driver to work?

I did a little more checking and the error codes are listed in the .h files for the CVI drivers. You should download the base version and bt versions to get both. Convert your error code to hex and you get BFFC0908. In rscmu200.h, an offset of BFFC0900 is defined and you get error code x008 which means "The function group is not assigned to a secondary address".

Is this the same issue you posted here as well? Have you tried Albert's suggestions?

I would make sure you have the latest VISA driver from National Instruments. Since NI doesn't support or maintain that driver, you might want to contact R&S to see if they have seen this type of issue with the driver they developed.
