can be changed to an arbitrary value by using the differential port
impedance conversion function and the common port impedance
conversion function.
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 the above figure.
Procedure to Turn On/Off Differential Port Reference Impedance Conversion Function
1. Press Analysis key, then click Fixture Simulator > Diff Z Conversion.
2. Click Diff Z Conversion to set the differential impedance conversion
function to ON.
You can only turn on or off Differential Port Impedance Conversion for all
of the balanced ports together, not for each port individually. If you want
to turn off only a specific port, set the reference impedance of the port to
the value in the above figure.
Procedure to Set Differential Port Reference Impedance
1. Press Analysis key, then click Fixture Simulator > Diff Z Conversion.
2. Specify the port reference impedance in differential mode.
3. Select the balanced port from Port 1 (bal) Real, Port 2 (bal) Real, or
Port 3 (bal) Real to set the differential port reference impedance in
"Real" format.
4. Select Port 1 (bal) Real and Port 1 (bal) Imag, Port 2 (bal) Real and Port2
(bal) Imag, or Port 3 (bal) Real and Port 3 (bal) Imag to set the
differential port reference impedance in "Complex" format.
5. Ports 1, 2, and 3 refer to the logical ports 1, 2, and 3.
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 the above figure.
Procedure to Turn On/Off Common Port Reference Impedance Conversion
1. Press Analysis key, then click Fixture Simulator > Cmn Z Conversion.
2. Click Cmn Z Conversion to set the common port impedance
conversion function to ON.
3. You can only turn on or off Common Port Impedance Conversion for
all of the ports together, not for each port individually. If you want to
turn off only a specific port, set the impedance of the port to the
value in the above figurerocedure to set common port reference
impedance
1. Press Analysis key, then click Fixture Simulator > Cmn Z Conversion.
