ps4000.xls

Post by postlund » Wed Jun 30, 2010 2:47 pm

I wan't to set my 4424 oscilloscope to trig when the measured signal goes above 5VDC on Channel A. What changes do i have to make to the VB code in the Excel document? I have made modifications but i can't seem to find any logic in the behaviour of the 4424. If i raise the signal slowly up above 5V nothing happens but if i make a quick change the 4424 trigs.

Hi

All you should need to do is set the thresholdUpper to your desired threshold value ((5V / range) * 32764).

The direction is already set to rising (2).
