Hi, I am using Labview 7 with a USB-GPIB interface to a gated photon counter (Stanford Research SR400) and I am operating channels A and B, triggered by an Optical chopper. I have got code which works perfectly recording data from channel A, and it instructs the counter to operate and record data on channel B, which it does but i now need to know how I write the code into LabView to read the channel B data into Labview. I have tried putting the read from A and B code in as a sub VI, but really I am not sure where I break the current code to put in a "for loop" or something for channel B like there is for channel A. I have only been using Labview for a few weeks and nothing I have tried so far works. Could somebody please let me know what structure I need to put in and where!
Thanks
