Figure 7-4 Reflection Impedance and Admittance Conversions
In a transmission measurement, the data can be converted to its equivalent series impedance or admittance
using the model and equations shown in
Figure 7-5.

NOTE Avoid the use of Smith chart, SWR, and delay formats for display of Z and Y conversions, as
these formats are not easily interpreted.
Input Ports Menu
This menu allows you to define the input ports for power ratio measurements, or a single input for
magnitude only measurements of absolute power. You cannot use single inputs for phase or group delay
measurements, or any measurements with averaging activated.
