continious AO for NI-USB 6008

[lav21]

Hi all,

I need to produce analog output (continious signal) - DC voltage (1V).

I have NI USB 6008, LabVIEW 8.0.

I get the "Requested value is not a supported value for this property?". I found a posting explaining the exact problem, but cant find how to change the the sine wave & the array from -2V to 2V to 0v to 4V. (can't open the vi - newer LabVIEW version)

Any hints?

THANKS

The modified example is right at the bottom of the page you linked. It's a version 7.1 VI. You should be albe to open it with no problem.

Even if you can't download it, you can follow the directions and modify the ranges. Also, if you are trying to output a dc voltage, you're using the wrong example. You just have to use a DAQmx Write of a single sample. The voltage will stay at whatever you programmed it to until you change it with another DAQmx Write. The DAQ Assistant can be easily used for this as well.
