I think you can use the 7854 to digitize the output of the sampling PIs. The place to ask is Tekscopes2. You might need to do a small mod to the 7T11A for proper triggering. I vaguely remember seeing it in a manual (7854 or 7T11A ??) somewhere.
As I remember the 7854 A/Ds don't work with the SA PIs, which generate their own displays, but do work with all other PIs.
