error -1074001422

[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,

I've been unable to locate any information about that specific error other than this thread. When you issue the command and the error occurs does the command actually make the change on the device or do what it is supposed to? Also, is this R&S driver one of the NI Certified drivers?
