📶 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.

🔍 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.

🛠️ 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.
