Setting measure setup
Before starting the Route Map measurement, you need to set Spectrum measurements displayed on the quick access and display
tab. See "
Configuring Spectrum Measurements " for more details.
1 If required, connect a GPS receiver to your CellAdvisor 5G for outdoor mapping. Indoor mapping does not necessarily need a
GPS antenna.
2 Tap the Setup ( ) icon on the side bar.
3 Tap Map Config to switch the Plot Point to GPS or Position or Time .
a To collect data/plot points automatically as you move around in a vehicle or outside (outdoor), select GPS and then tap to
switch to the Screen Mode between Map and Full .
With the Map setting, you can view only the collected points that can be seen within the boundary of the loaded map.
With the Full setting, you can view all the collected points of the route without the loaded map.
b To collect data/plot points manually in indoor layout without a GPS antenna, select Position .(If you tap the Start button
( ) on the right panel of the map, the Undo icon appears).
4 Tap to switch Plot Item to S-SS RSRP, P-SS RSRP , S-SS RSRQ , or S-SS SINR .
5 Tap Bandwidth/SSB SCS 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.

6 Tap Sync Raster/SCS 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.
The following table shows the sync raster offset range and sync SCS offset range per SSB SCS and sync raster/SCS
resolution.
