how do I create a constant current output with FP-AO-200, It uses an array as an input to the write vi for FP

If i use a single value in the 1x array, I get a random pulse, Im assuming I need to do an infinite population of the array to give me a dc current? Any ideas

The array input is supposed to contain a number of elements equal to the number of channels being targetted by the command. For example, if you write to "Channel 0" of a FP-AO-200, then you would have a single element in the array. Likewise, writing to the "All" channel means you need to have 8 elements in the array otherwise you will return error code 32800. The probable cause for you to see a pulse, is if you write a value in one interation of the loop, then on the next iteration write a 0.
