Over–the–Air Measurements (OTA) – LTE FDD Option 370, LTE TDD Option 371, 5G TF
Option 377, 5G NR / 5G NR EVM Conducted Option 378
How to Set Up Over–the–Air (OTA) Mode Settings
Then LTE Duplex Mode FDD TDD Selects the type
of LTE signal to be used in the LTE Coexistence
measurement (LTE FDD or TDD). Default = FDD.
Then
CC All Selects the which component
carriers are used in the measurement (CC0 to
CC7). Default = All.
Then Display Type Table Bar Selects how the
data is displayed (Table or Bar). Default = All.
Then LTE Setup opens a menu of softkey menu
choices to set the 5G NR signal values
(Freq/Dist, Meas Setup, and Trace. For details on
these softkey menus, refer to the hardkey
descriptions and their related softkeys in steps
5,
6, 7, and 11.
Then
5G NR Setup opens a menu of softkey
menu choices to set the LTE signal values
(
Freq/Dist
, Meas Setup, and Trace. For details on
these softkey menus, refer to the hardkey
descriptions and their related softkeys in steps 5,
6, 7, and 11.
——Then
EMF opens the EMF softkey menu (See
also,
“How to Set Up EMF Mode Settings
(Requires EMF (Option 358) and 5G NR (Option
378))” on page 400
):
Then
EMF Meas OFF ON Enables/disables EMF
measurements (Default = OFF).
Then EMF Triaxial [Sum All] ON Sets the axis (X,
Y, or Z) or axes (Sum All) of the Triaxial antenna
to be used in the EMF measurements (Default =
Sum All).
Then EMF Units dBuV/m Sets the EMF units
(dBuV/m)
——Then
Advanced opens the advanced softkey
menu:
Then Capture Length Sets the length in frames
for the current scan 4, 8, 16 24, 32, or 40 frames
are the choices (Default = 4 Frames).
Then
Drive Speed Sets the scan rate. Choices are
Low, Medium, or High (Default = Low). Use
slower speeds higher-mobility cases to track
faster changes in channel.
