Pintercept change for AD8319

Hi,

 

I want to change the Pintercept of AD8319. From the datasheet it says that I can use the formula

PINTERCEPT(dBm) = PINTERCEPT(dBV) − 10 × log10(Z0 × 1 mW/1 Vrms2 ) to get the new intercept.

 

Does it mean that I can just substitute my new Zo and get the new intercept from the formula?  I wondering where the PINTERCEPT(dBV) =2 dBV comes from. Is this still 2dBV when my Zo is not 50 ohms?

 

Thanks heaps!
