Stefan,
When you are doing the multiple signal process, will the collection time and averaging be done for all signals simultaneously or will there be separate Collect and Average controls for each channel?
If all channels will be done simultaneously, you can probably just make your arrays 2D with each channel in a different column. Each iteration of the loop will store the data in the next row (if Collect is True).
Notes on your VI: 1. You do not need the sequence structure. Dataflow controls when things happen. Your VI will work the same without it.
2. The two case structures wired to Collect Data could be combined into one.
3. Building an array inside a loop results in frequent memory reallocations. As the array gets large this will cause the program to slow down and will fragment memory. A better approach is to allocate memory outside the loop with Initialize Array and use Replace Array Subset inside the loop where the Build Array primitives are now. You will need to add another shift register to keep track of the next index to replace.
4. Loops should usually have a time delay to prevent them from grabbing all the available CPU cycles. Once you put in a real data acquisition process, that may provide the delay.
