Converting reference impedance of balanced port

Converting port reference impedance in differential mode

If you turn on the differential port impedance conversion function, the port reference
impedance in the differential mode is converted to an arbitrary value specified with this
function instead of the value in Figure 7-15.
Procedure to turn on/off differential port reference impedance conversion function
Step 1. - Press
Fixture Simulator
Step 2. Press
Diff Z Conversion
You can only turn on or off Differential Port Impedance Conversion for all the balanced
ports, but not for each port individually. If you want to turn off a specific port only, set the
reference impedance of the port to the value in Figure 7-15 .
Procedure to set differential port reference impedance
Step 1. - Press
Fixture Simulator
Step 2. Press
Port 1 (bal)
Step 3. Enter a value of the port reference impedance in the differential mode.

Converting port reference impedance in common mode

If you turn on the common port impedance conversion function, the port reference
impedance in the common mode is converted to an arbitrary value specified with this
function instead of the value in Figure 7-15.
Procedure to turn on/off common port reference impedance conversion
Step 1. - Press
Fixture Simulator
Step 2. Press
Cmn Z Conversion
You can only turn on or off Common Port Impedance Conversion for all the ports, but not
for each port individually. If you want to turn off a specific port only, set the impedance of
the port to the value in Figure 7-15 .
Procedure to set common port reference impedance
Step 1. - Press
Fixture Simulator
Step 2. Press
Port 1 (bal)
Step 3. Enter a value of the port reference impedance in the common mode.
