I am trying to write a vi that samples all four available channels (two on the 5142 and two on 5154) at the "same time" and stream all the data to a binary file. I am having an issue setting up the channels properly where they fetch the data at the correct rate.
My overall need is to sample each channel at 2MHz - so Im not breaking any speed records. The 5142 will have a 20V vertical setting while the 5154 has a 5 volt vertical. The sampleing can go direct to a file, but I would like one file for each channel if possible. Though if I combined each card to one file or even all four to one then its fine as well - I just dont want to impede the sampling speed due to file write. The file I have been working with is binary, as I find it fairly fast. I am open to other options.
Triggering is not an issue, as I would use the "start aquisition" method to start everything. While the four channels dont have to be exactly in sync, they need to be within a few micro seconds in order to keep things together when I go to do some analysis.
Any help would be appreciated.
