Also, I would like to point out , with all due respect you deserve, that measuring an electronics device output its not something “my universities” (as if I own any university, rofl) are concerned with.
Its merely something an engineer is concerned with. In this case, a good electronic engineer can get all the info he needs from a device.
Dont be so shocked, in this world you can copy any design and reverse engineer any protocol, for fun and profit 
It may be illegal to employ reverse engineering, but that’s another story.
Be nice, be happy enjoy our results, enjoy your PT practice, and forget about engineering and physics.
