AD8302 Phase Measurement

HI,

I want to use AD8302 board and I want to start characterize the board, I noticed in other discussions that when two signals are exactly the same the phase should be around 900 mv, right? because of internal phase shift? then again if I want to characterize the board | have to use a 90 degree phase splitter to make a 90 degree phase difference then again I get something around 900 mv? what happened to internal phase difference in this case?

I would appreciate if someone could help me understand it better.

Thank you
