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!
