Well, currently I am reading in a signal from an encoder, it is a counter input using the Angular Position reading and N number of samples. I am reading in 100,000 samples at 100kHz resulting in one second of data. In order to do this I have to use an external clock to pulse the reading. What I would like to do is have this demo run self-sufficient by having the DAQ board also produce the 'external clock' by using one of the outputs. I have tried it several different ways and I have yet to get it working correctly. I have tried using the DAQ analog output using a square wave with the desired frequency output, but I couldn't get the input (the angular position) and the output (pseudo external clock using the waveform) to match up and output and input at the same time. Is there a way I can do this, by any other means? Using file I/O, as in loading a file when the timing is needed? Or perhaps I am in the completely wrong direction, which very well could be.I also tried using a counter output to output the frequency needed but that did not work either. I have tried eveything that I could think of to get this self-sufficient. Any help and guidance would be greatly appreciated. Thank you very much for your time and effort.I tried the DAQ assistants also, but those prooved to be less helpfult hen using the base DAQ blocks in setting up my own sample channel and manipulating it that way.Michael Boyd

Thank you very much for the response. It seems that would be the case. I understand the multiple limits of the USB bus, computer, and the DAQ board itself. Thank you again for the answer.
