Capturing Digital Data X amount of time passed the buffer

[smcdaid]

Is there a way to capture Digital Inputs 40 ms after a trigger has occurred? I can do this in waveforms by setting the position out into some future number, but it seems in python I can only capture up to the number of samples I have set in the buffer, so I'm limited to my sampling rate * cSamples in time.. 

dwf.FDwfDigitalInTriggerSourceSet(hdwf, c_ubyte(11)) # T1

dwf.FDwfDigitalInBufferSizeSet(hdwf, c_int(cSamples))

dwf.FDwfDigitalInTriggerPositionSet(hdwf, c_int(cSamples)) 

 

Is there a way around this?

Hi @smcdaid

You can set it to higher number, above the device buffer size.
Like at 100MHz with buffer size 4000 and position of 4004000, you will get 4k samples starting from 40ms after the trigger, T+40ms+40us
