IviScope_ConfigureAcquisitionRecord and IviScope_ConfigureInterpolation fail

[Requiem_Q]

Hi All,

I set up my oscilloscope for an acquisition over TCP/IP using the IVI libraries.

Scope is a Tektronix DPO7354C.

I have no problems setting up Triggers and Channels but when I get to set the acquisition I have problems

This is my call sequence:

IviScope_ConfigureAcquisitionType (scopeHandle, IVISCOPE_VAL_NORMAL);                    //OK

IviScope_ConfigureAcquisitionRecord (scopeHandle, 0.001, 1000, 0.0);                                 //FAIL
IviScope_ConfigureInterpolation (scopeHandle, IVISCOPE_VAL_NO_INTERPOLATION);    //FAIL

I've an error on

IviScope_ConfigureAcquisitionRecord and IviScope_ConfigureInterpolation

If I comment on these two calls everything goes well and I acquire my waveform.

Could anyone tell me how to solve?

Thanks

Hi @Requiem_Q,

Could you please provide some further information on the errors you are receiving? What are the error codes and error messages? Screenshots would be helpful.

Hi @nestorl

The driver gives me no more information about these errors. (In other cases I have errors like "value not supported")
In the end I switched to low-level settings.

so I split 

IviScope_ConfigureAcquisitionRecord (scopeHandle, 0.001, 1000, 0.0);

into

IviScope_SetAttributeViReal64 (scopeHandle, VI_NULL, IVISCOPE_ATTR_ACQUISITION_START_TIME, start_time/*0.0*/);

IviScope_SetAttributeViReal64 (scopeHandle, VI_NULL, IVISCOPE_ATTR_HORZ_TIME_PER_RECORD, time_per_record/*0.001*/);

IviScope_SetAttributeViReal64 (scopeHandle, VI_NULL, VISCOPE_ATTR_HORZ_MIN_NUM_PTS, min_num_pts/*1000*/);

IviScope_ConfigureInterpolation (scopeHandle, interp_type);

the problem occurs with the settings VISCOPE_ATTR_HORZ_MIN_NUM_PTS and IviScope_ConfigureInterpolation

It's a problem I only have with a Tektronix oscilloscope, I have no problems with another tested brand.

The values entered are supported by the oscilloscope (and in any case I also tried the default ones.

At this point I think it's a problem with the Tektronix driver

Thanks
