Digilent Discovery Pro Trigger delay issue

[LJH]

Hello,

I am trying to use the FDwfAnalogInTriggerSourceSet to set my trigger. I am sending a signal from the wavegen out directly to the channel 1 input and reading. 

I set my signal to send out 1V at 500ms but I can see from the plots I am actually reading my signal at 510ms ~520ms. 

I have included my code below as well as a plot of what the digilent is seeing.

If I send in different amplitudes, the delay changes around a bit as well:

2V input:

0.1V input:

 

please let me know if I can remedy this!

Thank you!

Hi @LJH

See the following: ex1.py (changed to sine to be easier to verify)

If you are capturing less than 32Ki samples/channel you can use single capture mode.
You could use up to 32Ki samples for analog-out custom for higher resolution signal.
I recommend using the latest version sine beside other things it fixes some related to ADP3000 recording.
