How to Define a Cell or Cell(s) and Use OTA
LTE FDD, LTE TDD, 5G TF, 5G NR, and 5G NR EVM Conducted have only one
predefined view (Table). You can define measurements, which can be used to
display up to four different views (windows) simultaneously on the display
screen. You can select which type of data to display in each of the views from
the Trace menu.
Cell definitions consist of the following:
— Set frequency according to DUT requirements
— Define cell settings
— Define component carrier(s) (CCs) settings
Example: Using OTA LTE FDD or 5G TF, refer to:
— “Step 1: LTE FDD (Option 370), LTE TDD (Option 371), 5G TF (Option 377),
and 5G NR (Option 578): Component Carrier (CC) and Cell Defined” on
page 384
