I have a question about stopcondition data acqusition

[DrObb]

I used SWAnnalog trigger off ch 1 and have ch 1 and 2 on. I need to collect data 512 points each channel. How do I make the daq stop right after waveform (well, 1 for ch1 and another 1 for ch 2) were received. Right now, it keep acquire data several hits before it stops.

Hello;

The best way to accomplish that is to specify the number of points to be acquires to match the 512 points you need.

If you enter that number as the number of points to be aquired, you won't need to worry about the correct time to hit the stop buttom to stop the aquisition.

Hope this helps.
