How do I use a ref. trig. to start DAQ for multi-channels?

[Matt Kay]

I have bought a PCI-6259 which is capable of 16 double-ended channels and analog triggering. I want to be able to use one of the analog channels to trigger a reference trigger such that when the data is recorded, a certain percentage of the data points before the trigger are included as well. I have gotten to this far with one channel, but now I want to use the same trigger for that one channel to trigger the other 15 channels in the same manner. How would I go about doing this?

Matt,

Assuming that you are using LabVIEW, (or any other programming environment as a matter of fact) you can lump all of your channels into one task and apply the triggering to that one task.  All the parameters would be applied to all the channels.  For example, in LabVIEW, if you have a task you can just enter multiple channels into the "Physical Channels" control like ai0:8.  Once you do that the trigger will be applied to all the channels in the task.

Hope that helps.
