Monitor Virtual DAQ Channels

[zyoder4]

I've successfully created a virtual DAQ device (USB6212 BNC) in NI-MAX. I would like to use this virtual device to debug a MATLAB program, and I need to monitor the output channels of the virtual device. Is there any way to do this, or some virtual oscilloscope that would work? Thanks.

You just treat it as a normal DAQ.  For Analog Inputs you will get sine waves.  For Digital Inputs, you will get counting patterns.

Thanks for the reply. I'm wondering if there is a way to actually see the (voltage) value of each output channel in real time, as if you connected a physical oscilloscope to each output channel of the DAQ.

No, simulated devices don't have that level of sophistication.  You'll need to connect real DAQ hardware to be able to monitor output signals you're generating.

Perhaps if this idea ever got implemented: Interactive DaqMx simulation interface ... Be sure to give the idea a kudos.
