Chapter 7 Using 5G NR Signal Analyzer
Conducting OTA measurement
PBCH channel are packed as a single block that always moves together. SSB
should be detected first in 5G NR frame. See
criteria based on the operating frequency.

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
Table 45
resolution.
6
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.
7
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 in Step 4.

10 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.
11 Tap SSB Center Frequency and input the value using the on-screen keyboard.
12 Tap GSCN and input the value using the on-screen keyboard.
13 Tap to switch PCI (Physical Cell ID) to Manual or Auto.
14 Tap PCI and input a value from 0 to 1007 using the on-screen keyboard. The PCI
switches to Manual.

Tap Auto Preamp/Atten and switch SSB Auto Search to Start to set
preamp and attenuation automatically.
Tap Manual and switch SSB Auto Search to Start for manually setting
based on your need.
Start: to search SCS, type, and the number of SSB automatically. Once Start
is selected, the progress bar appears. If it fails to perform the auto search, a
fail message appears and the SSB switches to Manual.
Stop: to set the SSB periodicity based on the base station.
