Selecting mode and measure
To start measurement, do the following steps:
1 Tap 5G NR Signal Analyzer on the MODE panel.
2 Tap any measurement mode from the following choices:
Spectrum Analysis > Trigger Spectrum
RF Analysis > Channel Power , Occupied Bandwidth , Spectrum Emission Mask , ACLR , Multi- ACLR , or Spurious Emissions
OTA Analysis > Beam Analyzer , Carrier Scanner , Route Map , Beam Availability Index , Freq/Time/Power Variation , or
Multipath Profile
Modulation Analysis > Constellation
Power vs Time > Power vs Time (Slot) or Power vs Time (Frame)
PDSCH Analysis > PDSCH Constellation , EVM vs Subcarrier , or Allocation Mapper

Setting measure setup
After configuring spectrum measurement in " Configuring Spectrum Measurements ", you can set the measure setup to continue your
measurement. The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto
the instrument using the
Save/Load icons on the side bar.
1 Tap the Setup ( )icon on the side bar.
2 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.
