PXI or CRIO differential analog output modules

[craiguno]

Does NI have any differential analog output boards or do you just have to use two channels to create the differential signal?

Hello craiguno, 

What do you mean when you say differential analog output boards? Could yo tell me more about your application or what are your requirements?

I would like to provide a 200 mv (+/- 100 mv) differential signal to a differential voltage input.

Hello craiguno, 

If I am understanding correctly this might be what you are looking for:

NI BNC-2120
https://www.ni.com/en-us/support/model.bnc-2120.html

and here is the specification manual:

https://www.ni.com/docs/en-US/bundle/bnc-2120-getting-started/resource/372123d.pdf

Please take a look at page 9 where you can see the Using of Function Generator. 

Regards.

Ernesto.
