External Components List
In order to properly define the external compo-
nents value the following system parameters
have to be defined:

the line terminals "Zs" to which the return loss
measurement is referred. It can be real (typ.
600 ) or complex.
lent impedance of the line "Zl" used for evalu-
ation of the trans-hybrid loss performances
(2/4 wire conversion). It is usually a complex
impedance.
