skrf.network.Network.z0

Network.z0

the characteristic impedance[s] of the network ports.

This property stores the characteristic impedance of each port of the network. Because it is possible that each port has a different characteristic impedance, that is a function of frequency, z0 is stored internally as a fxn array.

However because frequently z0 is simple (like 50ohm),it can be set with just number as well.

Returns :

z0 : numpy.ndarray of shape fxn
