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 Lmax Sets the current half frame SS/PBCH blocks
indexing in ascending order in time 0 to (L
max
– 1). Choices
are 4, 8, or 64 (Default = Auto).
— Then More opens a menu for Capture Length, Drive Speed,
SS Meas DMRS, SSB Offset Detection, LTE Coexistence
(NSA / DSS), EMF, Advanced. See also, “How to Define a
Cell or Cell(s) and Use OTA” on page 384
.
——Then Advanced opens a menu for Capture
Length, Drive Speed, Phase Comp, SS Meas
DMRS. See also, “How to Define a Cell or Cell(s)
and Use OTA” on page 384
.
— 5G NR EVM Conducted NR:
— Then
Cell ID Auto Sets the Cell ID to Auto or to Manual
(default = Auto).
— Then Bandwidth Sets the FR1 / FR2 bandwidth (Default =
FR1 100 MHz).
— Then Resource Grid Opens a softkey menu to select the
component carrier and optionally export scan results to 5G
NR.
——Then
SCS Auto - the SCS value is coupled to the
center frequency and FR1 and FR2. Manual
choices are 15 kHz and 30 kHz. Default = Auto.
—— Then
Grid Start only settable when SSB Auto is
set to OFF. Default = 0.
—— Then Grid Size only settable when SSB Auto is
set to OFF. Default = 273.
——Then Export to 5G NR Setup – Export the current
scanned table of information to 5G NR.
— Then SSB
Opens a softkey menu to select the SSB settings
that are coupled to the Resource Grid SCS setting.
——Then SSB Auto-Detect OFF ON -
Enables/disables SSB Auto-Detect state. When
SSB auto-detection is enabled, the SSB offset,
SSB Case, Lmax, Periodicity and, optionally, SCS
are all auto-detected in the measurement. When
disabled, the settings can be set manually.
Default = ON.
——Then
SSB Offset
- Opens a menu to set the SCS
values.
