6.2.1.2 S-Parameter Wizard
The "S-Parameter Wizard" guides you through the setup of a standard multi-port S-
parameter measurement in a frequency sweep.
This dialog is not available for R&S ZNBT, or if a switch matrix is configured.
Access: TRACE – [MEAS] > "S-Params" > "S-Param Wizard..."
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 260.
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 263.
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
