Is it possible to output a floating voltage with the usb-6009?

[btcardwell]

Hello,

I was wondering if anyone knows how to output a voltage difference across AO 0 and AO 1 on the USB-6009 DAQmx without referencing ground.  Any help would be greatly appreciated.

Thanks,

Bryan

Hi,

Page 19 of the USB-6009 manual:

Shows that the internal DAC circuitry is referenced to ground so there is no way to internally isolate it/provide any reference.

Perhaps there is another way of doing the desired effect? I don't know the details of your application to suggest any.

Please feel free to ask further questions
