Outlines
đ¶ Introduction to 5G Signal Analysis
The video script begins with an introduction to 5G signal analysis using OneAdvisor-800 or CellAdvisor 5G, which share the same user interface. The presenter demonstrates how to access the main menu and select the real-time persistence spectrum to observe active signals and their power levels. The focus is on configuring the real-time spectrum within a specific frequency range, starting at 850 MHz and stopping at 900 MHz, and adjusting amplitude settings to remove attenuation and level the signal for analysis.
đ Configuring and Analyzing 5G NR Signals
The script continues with a detailed guide on configuring and analyzing 5G NR signals. The presenter explains how to adjust the amplitude by setting the attenuation to 0 dBs and leveling the signal to -30. The analysis involves identifying two 5G signals at 5 MHz and 10 MHz bandwidths. The presenter then navigates back to the main menu to select 5G NR signal analysis, starting with a carrier scanner to add and analyze multiple 5G signals simultaneously, regardless of their channel bandwidth differences.
đ ïž Beamforming and Signal Quality Analysis
The presenter proceeds to perform a beamforming analysis to obtain beam ID and cell ID, which provides insights into the number of beams and the transmitting radio. The script describes how to enable a second carrier at 884.9 MHz, identifying it as a DSS signal with a 10 MHz bandwidth, and searching for the SSB (Synchronization Signal Block). The analysis reveals the power level and quality of the signal, with the automatic detection of the SSB for both carriers, indicating a single beam transmission from one radio for each carrier.

[MUSIC]
Hello everyone, in these how-to test tips,
we're going to be talking about 5G signal analysis, supported by OneAdvisor-800 or
CellAdvisor 5G, both having the same user interface.
[MUSIC]
So first, I'm going to go into the main menu, and
I'm going to select the real-time persistence spectrum.
[MUSIC]
Basically here I want to see how many signals are active and
we have power levels.
So I'm going to go and configure my real-time spectrum on frequency.
And then I'm going to start at 850 megahertz.
And then I'm going to stop at 900 megahertz.
[MUSIC]
Then I'm going to be making some adjustments in amplitude.
So I'm going to remove the attenuation, by default is 20 dBs, so
I'm just going to put 0 dBs.
And second, I'm going to go into leveling.
So right now, I have it at 0.
I'm going to go down to -30.
And then I have this ability here of multiple signals, two of them are 5G.
One is at 5 megahertz and the other one is at 10 megahertz.
So now to have an analysis of these signals,
I'm going to go back into my main menu and select 5G NR signal analysis.
I'm going to start with carrier scanner.
This is going to give me the ability to add multiple 5G signals that I can analyze
at the same time, regardless if they have a different channel bandwidth.
So I'm going to go and make the configuration, and the first one,
it's going to be at 872 megahertz.
That is the one that actually has a 5 megahertz channel bandwidth.
And then I'm going to be looking for the beam information.
The second one,
the second carrier that I'm going to be enabling here, it's at 884.9 megahertz.
That's DSS signal and that's 10 megahertz wide.
And then I'm going to be looking for the SSB.
[MUSIC]
Automatically, we find the SSB, and as you can see now,
we have both of them in terms of power level and also in quality of the signal.
In addition, I can do a beamforming analysis.
Here, I'm going to be able to get the beam ID, as well as the cell ID.
So I know how many beams and which radio is transmitting.
In this case, only one beam is being transmitted.
[MUSIC]
On the other carrier, I can do exactly the same test and
obtain the cell ID and beam ID.
And yet again, it's only one beam transmitted coming just from one radio.
[MUSIC]

Thanks for watching. [MUSIC]
