NI-SCOPE error -223409

[Tevildo]

I've had an error in the NI-SCOPE driver (version 4.1.3), using the NI-5122 digitizer. The error occurrs in the niScope_SendSoftwareTriggerEdge function. The relevant sequence of commands I'm sending is:

iStatus = niScope_Abort(SessionID);
iStatus = niScope_ConfigureHorizontalTiming(SessionID, 380E6, 256, 0.0, 1, VI_FALSE);
iStatus = niScope_ConfigureTriggerEdge(SessionID, "0", 0.0, NISCOPE_VAL_POSITIVE, NISCOPE_VAL_DC, 0.0, 0.0);
iStatus = niScope_ConfigureChanCharacteristics(SessionID, "0", NISCOPE_VAL_50_OHMS, 0.0);
iStatus = niScope_ConfigureVertical(SessionID, "0", 0.2, 0.0, NISCOPE_VAL_DC, 1.0, VI_TRUE);
iStatus = niScope_InitiateAcquisition(SessionID);
iStatus = niScope_SendSoftwareTriggerEdge(SessionID, NISCOPE_VAL_SOFTWARE_TRIGGER_REFERENCE);       // iStatus = -223409

The return from niScope_errorHandler is:

Error FFFC974F.

The error does not occur if I call niScope_close and niScope_init after every acquisition, but I assume I shouldn't have to do this.

Hi Tevildo,

This is a known issue, you're right that you shouldn't have to call niScope_close and niScope_init after every acquisition, but for the time being that's the best workaround.

Thanks for the info.  What I've actually done is to get rid of the SendSoftwareTrigger call and put the instrument to free-run acquisition for the initial measurement, then change back to triggered for the rest of the measurements.  But I'm glad to know that this is a known issue.
