Chapter 7 Using 5G NR Signal Analyzer
Conducting OTA measurement
•
S-SS RSRP (Secondary Synchronized Signal – Reference Signal Received
Power) — linear average over the power contributions (in Watts) of the resource
elements which carry secondary synchronization signals
•
P-SS RSRP (Primary Synchronization Signal – Reference Signal Received
Power) — average power measurement through all the primary sync signals
•
S-SS SINR (Secondary Synchronization Signal – Signal to Interference Plus
Noise Ratio) — linear average over the power contribution (in Watts) of the
resource elements carrying secondary synchronization signals divided by the
linear average of the noise and interference power contribution (in Watts) over the
resource elements carrying secondary synchronization signals within the same
frequency bandwidth
•
S-SS RSRQ (Secondary Synchronization Signal – Reference Signal
Received Quality) — ratio of N x SS-RSRP/NR carrier RSSI. Here N refers to
number of resource blocks in NR carrier RSSI measurement Bandwidth
Setting measure setup
Before starting the Beam Analyzer, you need to set Spectrum measurements displayed
on the quick access and display tab. See
page 9
To set measure setup
1
Tap the Setup (
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 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. See
criteria based on the operating frequency.
3
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 41
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.
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 2.
