ceties Posted October 5, 2006 Report Share Posted October 5, 2006 Hello, I have following problem. I have DAQ card NI-PCI 6110, BNC 2110, DAQ 8.3, Labview 8.2, Win XP SP2. I have trigger impuls that appears each 100ms on PFI 0/AI START. Each time it appears I want to aquire 8000 samples from Ch0. At first I tried to solute it like in 01_trig.vi but it didn’t work because I was missing some trigger impulses. Then I found that this solution is very slow and for retriggerable acquisition must be used trick described here. Problem is that it doesn’t work (02_trig.vi). I tried to change number of samples and sample rate. If I have sample rate Fs=4M and number of samples Ns=8000 it doesn't capture any data (AvailSampPerChan is still = 0). But if I change Ns=100 it captures data. On the other hand when I change Fs=100k and Ns=8000 it starts data acquisition but when I capture 53th (sometimes less sometimes more) vector it stops capturing data but while loop still runs (with AvailSampPerChan=0). Set the timing of the counter to continuous doesn't help I appreciate any help Thanks! Download File:post-4360-1160058664.vi Download File:post-4360-1160058674.vi Quote Link to comment
