Generating a DC analog signal using 6009

[Justin Lin]

Hello,

I'm a senior at a UCI doing a mechanical senior design project and I am having difficult using the USB-6009 that was provided for us with LABVIEW. I am trying create a block diagram to generate a simple DC voltage that is controllable. (Like on the Front Panel using a boolean switch just turn the voltage on and off, very simple) Right now, I'm still trying to learn Labview but getting real frustrated with the data acquisition device because whenever I try to use signal express or DAQ assitant I always get an error or when I test a signal, I can generate a specified voltage but have no ability to set it to 0 on the front panel.

I tried looking for examples in the "Find Examples..." however none of the examples for Generate Analog Signal supports the USB-6009. I can't use them as a template either because theres a timing feature thats not supported by the USB-6009.

Are there any examples out there for generating analog signals using the USB-6009? This has been bugging me for weeks. I found a lot for acquiring signals but none for generating signals.

Please Help!

Thank you

Justin

The example called Gen Voltage Update should work. It will generate an analog voltage. Put the DAQmx inside a loop if you want.

If you get errors with something, you have to post the error code if you want help. Posting the code you have written is also recomended.

thank you! that did the trick
