• 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 ONE PORT CAL SETUP dialog box.
• A representative menu is shown below.
• The example procedures at the end of this chapter show examples of various TWO PORT CAL menus.
• MAIN | Calibration | CALIBRATION | Calibrate | CALIBRATE | Manual Cal | MANUAL CAL | 1-Port Cal | ONE PORT CAL

Completion Menu Buttons
For this example menu, the Port 1 Reflective Devices to the 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 TWO PORT CAL menu.
The Port 1 Reflective Devices button (shown above at #2) is now marked with a completion checkmark.
