Hi @MikeWatson
The difference I notice is that in the WF app the sampling rate is 80kHz and in you app 50kHz.
The 5V glitch may be filtered out by the lower rate average sampling.
Also notice the noise band. This is a simultaneous lower rate capture of min/max samples.
It indicates that you have higher frequency components between 4.6-5.2V and glitches down to ~2.5V and up to ?7V.
Depending in the sampling rate, the 5V trigger may capture at these higher frequency components.
1. Use the same sampling rate.
2. Try using the decimate filter for the trigger detector. This will look at the raw 100MHz samples rather than the default averaged samples at specified sampling rate.
FDwfAnalogInTriggerFilterSet(hdwf, filterDecimate)
Set the trigger level to at least 5.5V
