error -1074001422; rssmu_SetFMState

[Y3G]

Hi,

There is the following issue that causes an error while trying to set a R&S signal generator parameters programmatically.

I have downloaded the  dll from the drivers site of the Signal Generator (CVI drivers, rssmu_**)

There are two lines in the code I use :

    step 1) rssmu_status = rssmu_init((char *) ((LPCTSTR) m_ResName), (int)(m_Query), (int)(m_Reset), &instrSession);

    step 2) FT_CHECKERR (rssmu_SetFMState  (instrSession, VI_TRUE) , "rssmu_SetFMState");

After that an error ("-1074001422; rssmu_SetFMState) occurred and popped up (attached picture).

The NI-SPY indicated that there was no crucial error. (attached) The Vi session was closed properly

I am using a TCP/IP connection and other commands worked

What is the root of this error and how can we prevent it.

I'll be there on Monday to debug the issue.

Hi Y3G,

It looks like the error that you are seeing here is instrument-specific.  Perhaps this state is not being set correctly for the instrument model you have?  Does your user manual for this signal generator have any information regarding this error or a section on setting that FM state?  Thanks!
