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 Transmission Impedance and Admittance Conversions
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.
