Can PXI-4461 generate a square wave "intelligently"?

[arnold_w]

I am using LabVIEW 8.2.1 and I have a PXI-4461 Dynamic Signal Acquisition and Generation Module. I want to generate a simple square wave. Do I have to generate many thousands of samples manually (with the Square Waveform VI) and pass those to the PXI-4461 or is there a more bandwidth efficient and simpler way to tell the PXI-4461 to generate a square wave with a certain amplitude, offset and frequency?

Hi arnold_w,

Here is a simple example on how you can generate and output a squarewave on a PXI-4461.

Simulate Signal Express.vi is configured to generate a sqarewave which is then passed on to DAQ Assistant, which is configured to generate analogue output on the PXI-6641.

This is probably the most simple way to achieve what you are asking for.

have a look at this example:

C:\Program Files\National Instruments\LabVIEW 8.5\examples\DAQmx\Analog Out\Generate Voltage.llb\Cont Gen Voltage Wfm-Int Clk-Variable Rate.vi

which gives a good idea on wave form gen.

Ok, thanks!
