APPLICATIONS

Real-time spectrum analysis
The 5GPro Spectrum Analyzer is a real-time spectrum analyzer (RTSA) that provides continuous acquisition of RF signals with 100 MHz of analysis bandwidth. Quick characterization of wireless signals and detection of intermittent interference is now possible through the combination of RTSA persistence and spectrogram views.
Snap‑to‑Peak, the new patent-pending feature is an innovation in RF testing. By using the touchscreen, field technicians can identify interferers through a movable window which allows them to search for the highest amplitude interferer and attach a marker.
The audible-tone feature allows for customizable thresholds to help pinpoint interferers and external PIM. This feature can be used to operate the instrument hands-free when the user is busy holding a directional antenna.

5G SSB blind scanner
The 5GPro Spectrum Analyzer provides an automated 5G blind scanner within the 5GNR signal analyzer application. This scanner allows the user to scan for 5G frequencies, GSCN values and PCIs without any manual configuration. Scanning can be done for bands, current span or a specific customizable frequency range.

5GNR signal analyzer
A 5GNR signal analyzer supports the demodulation of 5GNR signals validating over-the-air (OTA) performance of cell sites and ensures smooth communication with user equipment.
Analyzing up to 64 beams and displaying the 12  strongest beams with the corresponding power measurements, the 5GNR signal analyzer provides several beamforming metrics.

• Physical Cell ID (PCI), Beam ID and SSB periodicity.
• Auto-detection of subcarrier spacing (SCS).
• Secondary synchronization – reference signal received power (SS-RSRP): linear average received power of each secondary synchronization signal (SSS) resource element.
• Secondary synchronization – reference signal received quality (SS‑RSRQ): ratio of SSS power over the total power of a given number of resource blocks.
• Secondary synchronization – signal to interference and noise ratio (SS-SINR): ratio of SSS over all noise sources, including interferers.
• Multi-PCI – filter by strongest and specific PCIs (up to 12 PCIs)

Spectrum analysis (TDD gated sweep)
Time division duplexing (TDD) is a transmission technique whereby uplink and downlink signals are transmitted on the same frequency using synchronized timed intervals. Both spectrum analysis and interference analysis for TDD require the use of a  measurement technique called gated sweep. This technique facilitates the visualization of uplink or downlink spectrum by displaying that data within a specified range of timeslots.
This technique allows the visualization of the symbol and slots in a frame, within a power vs. time graph, and the selection of uplink or downlink timeframes to further facilitate the visualization of uplink or downlink spectrum. EXFO’s patentpending TDD Sync, synchronizes with the 5G or LTE frame and prevents from the use of external GNSS references to avoid synchronization errors between the gating and the frame.

LTE analysis
LTE analyzer supports the demodulation of 4G/LTE signals validating OTA performance of cell sites and providing key metrics including:

• Sector and group ID
• Physical cell ID (PCI)
• Duplexing mode (FDD or TDD)
• RSRP (dBm)
• RSRQ (dB)
• RSSI (dBm)
• Multi-PCI – filter by strongest and specific PCIs

OTA RF measurements
Absolute time error (TE)
Absolute time error (TE) measurements can be made with the 5GPro Spectrum Analyzer by demodulating the radio signal and locating the position of the primary sync sequence (PSS) within the SSB. The absolute time position of the PSS is determined using EXFO’s existing SYNC module that can be inserted into EXFO’s FTBx-88260 module. By doing so, it is possible to determine the absolute TE of the base station.
The GNSS receiver used for OTA TE measurements supports 5 GNSS constellations providing worldwide coverage:

• GPS (USA)
• Galileo (Europe)
• GLONASS (Russia)
• BeiDou (China)
• QZSS (Japan)

TA‑SYNC‑PREMIUM
Integrate new best-in-class, very high accuracy GNSS receiver
±5 ns accuracy in under 20 minutes
90% quicker than any other tester in the industry
Stratum 3E oven-controlled oscillator (OCXO) for holdover

OTA TE measurements can be performed on FR1 or FR2 bands using the TA-FR1 and TA-FR2 modules, respectively.
The measurement results are presented in a tabular format, with data displayed for each PCI/Beam ID along with SS-RSRP, SS‑RSRQ, and SS‑SINR values.Additionally, statistical information is provided for minimum, maximum, and absolute TE values, all in nanoseconds (ns) and in a graphical format, showing its evolution over time.

Channel power
The Spectrum Analyzer efficiently gives a clear view on the spectrum and measures the channel power on a specified integration bandwidth range.
To perform channel power measurements, the root mean square (RMS trace detector) is used to average the power level for accurate readings. The Spectrum Analyzer simplifies channel power measurements for technicians on cell sites.
