The appearance and button availability of the calibration menus depends on the settings established in the CAL SETUP, CAL METHOD, LINE TYPE menus and in the associated dialog boxes that appear from the Edit Cal Params button.

Full Name
• REFLECTION RESPONSE Menu
The exact composition of the menu depends on the settings made on the CAL SETUP, CAL METHOD, and LINE TYPE menus and on the resultant REFLECTION FREQUENCY REPONSE CAL SETUP dialog box. A representative menu is shown below. There is one example procedure of a REFL. RESPONSE calibration in this chapter.

REFL. RESPONSE Menu - Refl. Freq. Resp. Cal. - 2-Port VNAs - Typical example
Modify Cal Setup
Select displays the CAL SETUP menu where the Edit Cal Params button provides access to the REFLECTION FREQ. RESPONSE CAL SETUP dialog box for the selected calibration method and line type.
Read-only display of the ports selected for the pending calibration.
Completion Menu Buttons
For this example menu, the Port 1 Reflective Devices, Port 2 Reflective Devices, Thru/Recip, and Isolation (Optional) buttons link to completion submenus where additional calibration procedures are performed.
For example, the Port 1 Reflective Devices button (shown below at #1) links to the REFL. DEVICES PORT 1 submenu. As each procedure is completed, the submenu button is marked with a completion checkmark. When all the procedures on the submenu are completed, use the Back button to return to the REFL. RESPONSE menu.
The Port 1 Reflective Devices button (shown above at #2) is now marked with a completion checkmark.
Port 1 Reflective Devices
When selected, the REFL. DEVICES PORT 1 menu appears where each button represents a completion task. When ready for the task, click the button, and the instrument performs the calibration. When the calibration task is successfully completed, the button is marked with a completion checkmark. When all tasks are completed on the menu, return to the REFL. RESPONSE menu.
Port 2 Reflective Devices
When selected, displays the REFL. DEVICES PORT 2 menu where each button represents a completion task. When ready for the task, click the button, and the instrument performs the calibration. When the calibration task is successfully completed, the button is marked with a completion checkmark. When all tasks are completed on the menu, return to the REFL. RESPONSE menu.
Done
This button is unavailable until all calibration tasks have been successfully completed. When available, select the button to return to the CALIBRATION menu when the Cal Status is set to ON.
