Multiple analog inputs with different configuration RSE/Differential

[JackT]

Hi

Can anyone advise how to measure two analog inputs with different configurations using a USB 6009?
I am aware of the syntax to create to virtual channels for the DAQmx Create Virtual Channel(s) so I have created two channels using Dev3/ai0:1 but I would like the first channel to be RSE and the second to be Differential.
So far I have not found any way to specify the configuration for the separate channels.

Any ideas much appreciated!

Have you tried this??

Hi

Thanks for the response.

I have just tried as you suggest using the DAQ Assistant (creating two channels and setting the configuration differently) and this seems to work.

I prefer to use the 'low' level vi's so still curious to know if there is a way to set the configuration using them.

Cheers

Well, you can always skip the very first node (which is DAQmx Create Task.vi), I just kept it for elaborating the concept.
