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 TRANSMISSION FREQUENCY REPONSE CAL SETUP dialog box. A representative menu is shown below. The example procedures in this chapter show one example of a TRANS. RESPONSE menu.
• MAIN | Calibration | CALIBRATION | Calibrate | CALIBRATE | Manual Cal | MANUAL CAL | Reflection Freq. Response | REFL. RESPONSE
REFL. RESPONSE Menu – 4-Port VNAs – Typical example (1 of 2)
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.
Other Menu Buttons
For this example menu, the buttons below Port Selected to the Isolation (Optional) button each display calibration completion submenus. Once the calibration steps on each submenu are complete, these menu buttons are marked as completed.
Done
This button is unavailable until a successful calibration procedure has been completed. When available, it returns to the CALIBRATION menu where the Cal Status button is set to ON.
