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 FOUR PORT CAL menu.
The Port 1 Reflective Devices button (shown above at #2) is now marked with a completion checkmark.
Port 1 Reflective Devices
When selected, provides the PORT 1 REFLECTIVE DEVICES menu. 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 ONE PORT CAL menu.
Thru/Recip
When selected, displays the THRU/RECIP menu. When all tasks are complete, return to the ONE PORT CAL menu.
Isolation (Optional)
When selected, displays the ISOLATION menu. When all tasks are completed, return to the ONE PORT CAL 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.
The Edit Cal Params dialog boxes are populated with controls and fields that vary depending on the settings made in the MANUAL CAL, CAL SETUP, CAL METHOD, and LINE TYPE menus. Dialog box examples are:
