Characterization is the process of calculation of S-parameters table for all Module states.
User characterization of the Module is required if the Module connectors were modified using the adapters. The new device, including the Module and adapters, is characterized.
Before performing the user characterization of the two-port Module, ensure that the two-port VNA calibration has been performed with the port setup matching the Module.
Before performing the user characterization of the four-port Module, ensure that the four-port VNA calibration has been performed with the port setup matching the Module.
The Module is characterized together with its adapters. To save the characterization, do not disconnect and reconnect the adapters which were characterized with the Module. If the adapters are disconnected, the user characterization should be performed again.
User characterization procedure in the VNA software:
1. Press the calibration softkey in the software main menu.
2. Select automatic calibration in the resulting menu.
3. Press the characterization selection softkey in the autocalibration menu.
4. Select one of three user characterizations in the characterization menu.
5. Select the Module orientation method by pressing the orientation softkey in the autocalibration menu. It is recommended to use automatic orientation.
6. Start the Module characterization by pressing the respective softkey in the autocalibration menu.
7. Specify the following information in the pop-up dialog box:
•Operator’s name.
•VNA model.
•Characterization location.
•Connector types.
•Adapters connector types.
8. Press the save softkey to complete the Module user characterization.
The user characterization procedure is shown in the figure below.

Detailed information on the Module user characterization and the names of all softkeys for all VNAs can be found in the VNA Operating and Programming Manual.
