Dear All
I want to multi-channel DAQ with analog triggering.
I could acquire one channel data, trigger to one channel data and acquire two channel data at the same time.

As the next step, I tried multi-channel DAQ with analog triggering by combining one-channel triggering VI and two-channel DAQ VI(as the attached).
Input Physical Channel is ai0:1 and these ai are same sine-function(2V peak-to-peak).
I want to trigger signal of ai0 by the value in "Trigger level0" and to trigger signal of ai1 by the value in "Trigger level1".
Now, I set 0.5 to "Trigger level0" and 0.8 to "Trigger level1".
According to output dat file,
1. The signal "ai0" and "ai1" are triggered at 0.5V and 0.8V, respectively.
2. Some triggered signal only triggered at 0.8V are discontinuity(like /data/Discontinuous.png).
3. Same signal triggerd at 0.5V or 0.8V is alternately displayed at wave form graphs("Triggered Data 0" and "Triggered Data 1") in the front panel(like /data/FrontPanel.png).
Why 2 and 3 are occured and How can I improve that?
