Changing the Reference Impedance for N-Port Data

You can change the reference impedance for the S-parameter data in an N-port data file. This is done under the Port Impedance tab in the N-Port Data dialog box. You can apply the same impedance to all ports or a different impedance to each port.

1. Click the Port Impedance tab in the N-Port Data dialog box.

2. To apply the same reference impedance to all ports, do the following:

a. Select Simple Port Impedance.

b. Type the impedance value in ohms.

c. Select Admittance if you want Designer to calculate the admittance matrix, the inverse of the impedance matrix, based on the value entered.

d. Click Update.

3. To apply a different reference impedance to each port, do the following:

a. Select Set impedance for each port.

b. Select a port from the list.

c. Select Impedance or Admittance, then type the real and imaginary parts of the impedance value in the Real and Imaginary text boxes.

d. Click Update.

Repeat these steps for each port.
