I looked at the vi that you sent me in detail. What exactly is it doing? Is it triggering a single channel at a specific level? If yes,why does it need several channels? or is it using one channel to trigger another channel? I am a beginner and I have a lot of question regarding this program
What is "when inside window" and "when outside window" and window amplitude in the case structure mean? it says that "inside window" means data<=window amplitude+level and data>=level-window amplitude(WA), outside window means data<=level-WA or data>=WA+level. What are these range mean?
Also, when rising edge is selected in the case structure window, it's asking if data<level-WA, if it is true, it is above level, if it is false, it is asking if it is first time called, if that is true, condition is connected to it, which I don't understand, and if it is false, shift register is connected. What does the shift register symbolize in here? Next, inside the case structure window, the true or false switch is turned to false and connected to stop and the next case structure window. What does this false switch symbolize? Next, this false is connected to another case structure, does this mean the case structure is automatically false?
Why is all the rising edge, falling edge, above and below level, inside and outside window connected to the next structure? Does that mean that when these are are true, the trigger is detected? I am very confused about this program and I don't know how to use this program to write a program to meet the requirement that I specified in the first post.
I am very new to labview and this program is frustrating me very much. Could you please answer these questions? Thank you very much.

Erik,
also, many people from NI recommend me to buy a M series daqmx board to trigger a counter from Channel index, do you think I need that? Thank you.
