Measure time difference between two points (py)

[RealPersonIPromise]

Hello, 

I am trying to measure the time between a rise and a fall (or vice versa) through python. I am trying to play around with the waveform sdk application and am looking for a way to measure the two spots automatically instead of manually moving the x cursors. I would like to translate this into python.

Hi @RealPersonIPromise

You could use the built in measurement and Script tool to automate things.
These measurements are not available in the API/SDK only in the app. For custom application data processing needs to be implemented.

Thank you for the information. Is there a way to grab the time values using py, such as when we export data, we can save the table with time and channel information? Or can we only get the channel information

Hi @RealPersonIPromise

The AD2 provides only software time but for newer devices AD3, ADP3X50... high precision T0 trigger time is returned by the following function, so the samples will be timed as T0 + sample position / capture rate, or for more accurate value T0 - FDwfAnalogInTriggerPositionStatus + sample index / FDwfAnalogInFrequencyGet
