How to Set Up Over–the–Air (OTA) Mode Settings
——Then SSB Case – Sets the SSB Case when SSB
Auto-Detect is disabled. This setting is coupled
to the Resource Grid SCS setting. Choices:
15 kHz SCS - Case A, 30 kHz SCS - Case B & C,
120 kHz SCS - Case D, and 240 kHz SCS - Case
E.
——Then
Lmax – Sets the Lmax when SSB
Auto-Detect is disabled. This setting is coupled
to the Bandwidth setting. Choices: an FR1
bandwidth is selected, 4 and 8; When an FR2
bandwidth is selected, 64 is available.
——Then
SSB Periodicity – Sets the SSB Case when
SSB Auto-Detect is disabled. Choices: 5 ms,
10 ms, and 20 ms.
— Then
Results –> Setup Opens a softkey menu to select the
component carrier and optionally export scan results to 5G
NR.
——Then CC CC0
- Selects the cc signal information
to be scanned (CC0 to CC4). Default = CC0.
——Then Copy to Manual Setup - Selects the cc
signal information to be copied to the manual
SSB.
——Then
Export to 5G NR Setup – Export the current
scanned table of information to 5G NR.
SCS Common
The signal sub-Carrier Spacing
Common setting is coupled to the
Bandwidth setting. When an FR1
bandwidth is selected, 15 kHz &
30 kHz SCS are available; When an
FR2 bandwidth is selected, 60 kHz
SCS & 120 kHz SCS are available.
RB Offset
Sets the Resource Block (RB) offset
of the signal SSB relative to CRB0.
Choices: Min: Dynamic. Varies based
on the Resource Grid Start setting.
Max: Dynamic. Varies based on the
Resource Grid Start and Grid Size
settings.
kSSB
Sets the kSSB of the signal SSB.
Choices: Min: 0
Max: Dynamic. Varies based on the
Resource Grid SCS setting.
