S-Parameter Wizard
The "S-Parameter Wizard" guides you through the setup of a standard multi-port S-
parameter measurement in a frequency sweep.
Access:
TRACE – MEAS > "S-Params" > "S-Param Wizard..."
The measurement comprises the following stages:
1.
Select the test setup
Choose the port setup of the analyzer according to the port configuration of your
DUT and connect the DUT to the selected analyzer ports. This step corresponds to
the "Predefined Configs" tab of the "Balanced Ports" dialog; see
2.
Define 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 corre-
sponds to the "Reference Impedance" tab of the "Balanced Ports" dialog; see
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 4.3.6, "Reference Impedances"
3.
Select the measurement parameters and the diagram areas
Choose an S-parameter or a group of S-parameters to be measured and dis-
played. The measurement parameters are displayed in separate diagram areas:
