I am trying to capture data from both channels of two PXI-5152 high speed digitizers simultaneously. I have only been using LabVIEW for about 2 weeks, so I am not entirely familiar with it yet. I understand how to capture data from both channels of only one 5152 at the same time but need to use all four channels. I have been using the Save to File example that comes with LabVIEW 8.5 to help me get as far as I am. Also, in the Front Panel I would like to give the user the option of using one or both of the digitizers. I can replicate the current "resource name" and "channel" configuration but then I don't know how to add the option of "none" to the pull down menu for resource name. Any help is appreciated!
A copy of my file in its current state is attached.
