Time Delay NIScope not working

[al0909]

Dear NI Community, 

I am developing a TestStand sequence where I capture 2 waveform with my scope. I am using a PXIe5110 and NI Scope for that. I have noticed that the Time Delay between the 2 channels couldn't be measured and it leads to an error. Going in InstrumentStudio to visualize the waveforms, I have noticed that regarding the acquisition was going well. Using the cursors, I also obtain the value that I want. 

However, when I try to measure it through the measurement window below, nothing appears for the Time Delay. 

Is there something in the configuration that I can do with NI Scope to correct that ?

Thanks in advance for your answer !

How exactly are you using the NI Scope driver to capture the signals? did you code anything in one of the supported ADEs (LV, Py, C# etc.,)?

Please share your code and how you measure the time delay.

Dear santo_13, 

Thanks for your answer. I am using NI-Scope drivers in generic steps as I am working with a Hardware Abstraction Layer, that's why it is complicated to share the code entirely. 

However, by equivalence, I developed quickly a VI reusing NI-Scope the same way I used it in the HAL and in my TestStand sequence. As you can see, I am using the Read Single Measurement to retrieves the Time Delay. In my sequence, this function causes an error. And in InstrumentStudio, I don't see any results as the picture showed it.

Thanks a lot in advance
