Analog Discovery 2 API trigger setting

[AlexMark6]

My vendor is writing wave measuring system by AD2 API for our project.
He said that the trigger setting does not work well compared to Waveforms application.
Concretely, we want to start to get wave data at the beginning of the wave swing start point, but sometimes data getting starts before the swing start point.
He says the Waveforms application does not fail as API.
Can anyone teach me the certain triggering method?

Hi @AlexMark6

Are you using trigger on analog input ? If so, are you using hysteresis for the this ? FDwfAnalogInTriggerHysteresisSet
The WF app by default, with Auto option sets this to 1/100th of pk2pk range.

Hi attila

I was surprised by your quick reply.

I transfer your answer to the vender soon. (Unfortunately, I cannot write API. I can only write script. So I cannot test your advise for myself.)

Thank you.
