How do I get an accurate peak to peak reading using labview?

[crash_override]

I have a very simple vi to generate a 100khz signal and then read the peak to peak but this thing seems to extremely inaccurate. I'm getting peak to peak readings that are way off and so is the rms. I even have tried to make a running average for more consistent values but it's still off.

Hi @crash_override,

I received the following details from somebody more familiar with the WaveForms and LabVIEW integration:

This roughly gives the peak-to-peak and rms values of your signal. If you want to measure for channel 2, just extract the second element of the output array.

Thanks,
