h Tap the Bandwidth/SSB SCS box and select the Setting in the pop-up window based on your need. SSB is abbreviation
for Synchronization Signal Block or SS Block and it actually refers to Synchronization PBCH block since the
synchronization signal and PBCH channel are packed as a single block that always moves together. SSB should be
detected first in 5G NR frame.
The following table shows the setting criteria based on the operating frequency.

i Tap L to set the maximum number of SS-PBCH blocks within a single SS burst set (A set of SS being transmitted in 5 ms
window of SS transmission) among 4 , 8 and 64 .
Refer to the selection criteria based on the table, h .
j Tap the SSB Period box and select the options from 5 ms , 10 ms , 20 ms , 40 ms , 80 ms , or 160 ms .
The SS burst period (SSB periodicity) is defined by each base station and network configurable. 20 ms is the default for
the initial cell selection.
k Tap the Auto Search box and select the options from Auto Preamp/Atten or Manual .
Auto Preamp/Atten to set preamp and attenuation automatically or Manual for user-defined settings.
l Tap the Start button in Auto Search box to search SCS, type, and the number of SSB automatically or the Stop button to

Once the
Start button is tapped, the progress bar appears.
m Tap the SSB Frequency button and input the required value using the on-screen keyboard.
n Tap the GSCN box and input the required value using the on-screen keyboard.
Based on the GSCN input frequency, the SSB Frequency, Sync Raster Offset, and Sync SCS Offset are automatically
changed.
o Tap Sync Raster Offset box to manually set the required value using the on-screen keyboard.
p Tap Sync SCS Offset box to manually set the required value using the on-screen keyboard.
3 If you select LTE, do the following step:
a Tap the Center Frequency box input the value using the on-screen keyboard.
b Tap the Channel Standard box and choose one from the pop-up window and tap the Apply button.
