I need to sample data from four analog input channels. I am using NI USB 6229. It is very simple application (what i think). The sample rate is 40k for 2 seconds. I am using "Write to spread sheet" to write data to file. The vi runs fine when i use only one channel. It writes array of 80k data points in the txt file. Problem:When I use multiple channels, it only returns the last samples. for example if I use four channels, it returns four it gives four values instead of expected four arrays one for each channel.
