How to pass actual waveform data from NIScope to a TestStand variable?

[NI_6509]

We are trying to pass the actual waveform data that is created by function niScope_Read to TestStand so that it can be processed/analysed in later subsequences and steps.  "wfm" is the actual parameter we are trying to get into TestStand. (doc snippet pictured below)

We are not having any problems passing in the other niScope_Read output parameters. However, we are having trouble with this one.  We understand that it is defined as a pointer to ViReal64 array but are not fully understanding how to set up our TestStand variable/parameter expression to be able to pass and store this information in TestStand.

We have stepped into the code module while creating watches for the wfm variable.  In the LabWindows/CVI environment we do see that the expected waveform data is being created and populated at the wfm pointer location, BUT the problem is passing it back to TestStand

Does anyone have any insight or tips to help with this?

Thanks
