The wizard proceeds in the following steps:
1. Select the test setup.
Choose the port setup of the analyzer according to the port configuration of your
DUT. Then connect the DUT to the selected analyzer ports.
This step corresponds to the "Predefined Config" tab of the "Balanced Ports" dia-
log; see"Predefined Config tab" on page 399.
2. Define the port impedances.
Assign reference impedances to all physical and balanced test ports selected in
the previous step. The reference impedances can be complex.
This step corresponds to the "Reference Impedance" tab of the "Balanced Ports"
dialog; see "Reference Impedance tab" on page 400.
Tip: The default reference impedance of the physical analyzer ports is Z
0
= 50 Ω.
The default reference impedances for balanced ports are derived hereof. You do
not need to change this value unless you want to renormalize the port impedances;
see Chapter 9.3.2, "Reference impedances", on page 217.
3. Select the measurement parameters and the diagram areas.
Depending on the test setup selected in step 1, the wizard offers different sets of S-
parameters. Each S-parameter trace is displayed in a separate diagram. For trans-
mission parameters, the wizard always selects dB magnitude format. For reflection
parameters, you can select between Smith or dB magnitude format.
Tip: You can always use the "Back" button to return to previous wizard steps and
modify your settings.
4. Select the sweep settings.
