Multible Channel Pretrigger

Hi all,

 

I am working on a labview daq software with a NI 9220 device  i would like to set triggers with threshold on 8  channels, as soon as a voltage level reach the threshold it  should  trigger and give me pretrigger and post trigger samples. 

Otherwise i would calculate some values with the continuous data (RMS, MinMax) and write it to file.

 

i was looking at this example:

This looks similar to my wishes, but it only has one physical channel, i was wondering if its possible to look at more than one channel, to get my requirements. 

 

thank you very much 

best
