List of PXI AO modules with internal channels

[Xenorollmops]

Hi Y´all,

Can anyone tell me which of the currently availabel AO-Modules for PXI do support internal channel read out. 

If you can tell me which value in the spec, I need to search for, that wold be helpful as well.

Thanks in advance.

Kind Regards,

So, you want to read back the value you commanded the AO card to generate?

Hi,

Yes, that's right. I want to read back the actual value the AO is currently outputing.

I know that the PXIe-4322 does not support it, but I do not know which card does.

Cheers

There is no AO module that allows you to readback the generated voltage without looping it back to a AI channel.

You can achieve the equivalent by wrapping up the DAQmx Write API with a custom layer that keeps track of last updated AO value and you can query the wrapper instead of the driver.
