multiple channel trigger

[tj.diego]

I want acquire from 4 channel using a ni 6110 and bnc 2110, but instead to use a single trigger i would like to use a multiple trigger, one for each channel and if even just one of them is verified acquire all!

i tried to acquire  continuously and trigger the signal by labview but is too slow and i lose samples.

do you have any idea?

Thanks

Hi tj.diego

Triggers are configured on a per task basis. All line configured in the same analog input task will trigger the same. For each task (AI or AO or DIO or Ctr), you have the option to configure a start, reference, and pause trigger. 

You can't set more than a trigger for your Ai task. if your triggers are digital signals, you can try to realize a digital OR, reading with the digital lines the signals and starting the AI task as soon as the ReadDIO returns a TRUE.

As an alternative you can try to implement what is suggested into KB 1VQ9J3LL.

I hope this can help you!

Good work

Hi Hudson,

thanks for reply,

unfortunately my signals are not digital, so i'll try your second solution but i'm afraid that at 5MS/s i can lose something!

by the way i didn't get the sentence about the ATCOUT signa, could you be clearer?

thanks
