So I found this example of a 2 channel oscilloscope on the ni website, but I can't get the triggering to work, I'm using a USB 6009. I would like to use a function generator's ttl function as a trigger, but whenever I switch to a trigger mode the program stops acquiring data. Also, I was wondering if anyone could tell me what the sampling rate would be for this device and program.
if the attachment won't work he is the link to the site I got it from.
