Converting the Port Impedance of the Measurement Result

The measured value obtained by using a port impedance of 50 Ω can be converted into a

measured value at an arbitrary port impedance.

Figure 7-3 Port impedance conversion function

Converting the Port Impedance

Step 1. Press - Fixture Simulator - Port Z Conversion.

Step 2. Specify the port reference impedance for the required port.

• Select

Port 1 Z0 Real, Port 2 Z0 Real, Port 3 Z0 Real, or Port 4 Z0 Real to set the port

reference impedance in “Real” format.

• Select

Port 1 Z0 Real and Port 1 Z0 Imag, Port 2 Z0 Real and Port2 Z0 Imag, Port 3

Z0 Real

and Port 3 Z0 Imag, or Port 4 Z0 Real and Port 4 Z0 Imag to set the port

reference impedance in “Complex” format.

Step 3. Press

Port Z Conversion to change the port impedance conversion function to the ON

state.

Step 4. Press

Return.

Step 5. If

Fixture Simulator is OFF, press the key again to turn it ON.
