Hi
I need to run 2 USB devices to acquire a voltage and output a voltage. I'm using a USB-6000 to acquire a 0-10V signal and a NI 9263 (with NI USB-9162 carrier) to outup a voltage. The output need to accurately replicate a sine wave up to 150Hz. The input just need to respond to a user turning a dial (a response time of 200ms would be fine)
I have created seperate applications for each of these devices and managed to get these to run as I want. However when I try to combine the code into a single vi the speed of of the resulting application is much slower (I get about 1 iteration per second in the vi's main while loop).
Is there any reason these 2 devices should not work together in a single application a the sort of speed I require?
If required can send a copy of the vi I have created. I am a Labview newbie so it's likely that the problem is that my program is inefficient.
Thanks
