IviScope_ConfigureAcquisitionRecord and IviScope_ConfigureInterpolation fail

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
