Hello,
Analog triggering is NOT available on the DAQPad-6015. Therefore you cannot set DAQmx to perform an Analog Edge trigger. Even though this can not be done in hardware you can still perform different actions based on the software analysis of the data.
Therefore, you can use LabVIEW to analyze the data from one channel. You will start acquiring data from both channels using DAQmx. Then depending on what the data is for one channel you could perform different actions, possibly by using a case structure, and either hide or display the second set of data. There are many different techniques and VIs you can use to analyze your data. The array of data returned from DAQmx can be manually analyzed by any custom subVI that you would like to build because you can look at each individual data point. However there are many subVIs already built in LabVIEW that should save you some time. Many of these VIs are under the Analyze menu in the Functions Palette. I really can't tell you a single VI that will solve your problem since there are many possibilities based on how your program is designed. The express VIs are generally easy to configure and use but there are also many other non-express VIs that are useful as well.
