Issue Details

I would like to get the frequency response of a PCI-5114 PCI Oscilloscope Device using the niScope Get Frequency Response.vi function in LabVIEW.
 
I get the error message with the error code -1074135022, that the "Attribute or property not supported".
 

Solution

Use the niScope Get Frequency Response.vi only together with such hardware, that supports onboard signal processing (OSP).

According to the LabVIEW Help, the niScope Get Frequency Response.vi gets the frequency response of the digitizer for the current configurations of the channel attributes. This VI can be used only with high speed digitizers that support onboard signal processing (OSP). Since PCI-5114 doesn't support OSP functionality, the readout cannot take place.

In the opposite case, when the device supports OSP, like the PXIe-5622, the readout succeeds.
