Tap Sync Raster Offset to set the sync raster resolution to 180 kHz (FR1) or to
720 kHz (FR2) for carrier frequency center using the on-screen keyboard. See

resolution.
4
Tap Sync SCS Offset to fine-tune the offset using the SCS. See
for the sync raster offset range per SSB SCS and sync raster resolution.
5
Tap SSB Center Frequency and input the value using the on-screen keyboard.
6
Tap GSCN and input the value using the on-screen keyboard.
Based on GSCN input frequency, the SSB frequency changes automatically.

Tap SSB Periodicity and select the options from 5 ms, 10 ms, 20 ms, 40 ms, 80
ms, 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.
10 Tap Slot Formats and input the value from 0 to 55 using the on-screen keyboard.
The slot format means how to use one slot between downlink and uplink.
11 Tap to switch Link to UL or DL.
