The integrated field test system allows wireless professionals deploying 5G NR to conduct more accurate measurements than conventional instruments using 2D data to ensure 5G NR networks meet performance specifications both indoors and outside.

Commercial wireless service providers, public safety entities, and wireless subcontractors can use the Field Master Pro MS2090A with NEON to ensure reliable communications everywhere, from wide open spaces in the countryside to the middle of a large city. NEON can also be used to ensure network performance inside office buildings, on trains in underground tunnels, and in large public spaces such as sports arenas, shopping malls, and airports.

When used outside and in sight of GPS satellites, the system will use GPS data to continuously track the user while making measurements. Where GPS is not available, the TRX NEON solution using a body-worn tracking unit and Android-based software delivers 3D location and mapping of measurement data inside buildings, underground and in other GPS-denied areas.

In addition to the unique 3D tracking capability, NEON Signal Mapper provides exceptional indoor coverage mapping capabilities. It eliminates the need to manually perform “check-ins” at each test point, provides more data than what can be gathered manually, and removes data recording errors caused by “guesstimating” locations in large buildings. NEON delivers actionable data in areas not easily analyzed such as stairways and elevators, enables quick analysis of signal coverage, and drives faster problem resolution by providing the industry’s only geo-referenced 3D visualization.

The combined system leverages the industry-leading performance of the Field Master Pro MS2090A, which has the highest continuous frequency coverage up to 54 GHz, real-time spectrum analysis bandwidth up to 100 MHz, and a ruggedized design to withstand the demands of field test. Its best-in-class performance includes Displayed Average Noise Level (DANL) of <-160 dBm, Third Order Intercept (TOI) of typically +20 dBm, and phase noise of typically -110 dBc/Hz at 100 kHz offset.

5G NR demodulation is supported by the Field Master Pro MS2090A. It provides cell ID, beam ID, RSRP/RSRQ, SINR, and EVM in all 5G bands (sub-6 GHz [3.5 GHz] and millimeter-wave [28 GHz and 39 GHz]). It can also be used to conduct compliance testing, including EIRP, spectral emission mask, and time offset, as well as harmonic and spurious testing. Real-time spectrum analysis spans up to 100 MHz are possible for accurate interference monitoring in the cellular bands or full ISM band.
