The SHA860A's 5G NR OTA mode demodulates signals to extract key parameters, such as frequency, physical cell identity (PCI), SSB index, frequency error, and error vector magnitude (EVM) for the SSB portion, which are visualized using constellation diagrams. This functionality is vital for optimizing non-standalone (NSA) 5G deployments, as it ensures seamless coordination between LTE and 5G networks.
The LTE OTA testing function provides comprehensive demodulation metrics, including PCI, sector ID, cell group, frequency error, time offset, synchronization status, and power levels (PSS/SSS/CRS/PBCH), along with EVM measurements and constellation diagrams. By analyzing signal quality, channel performance, and interference across multiple cells, technicians can implement targeted strategies to improve network efficiency and user experience.
With a real-time bandwidth of up to 110 MHz and a processing speed of 300,000 FFTs/s, the SHA860A captures transient signals as short as 3.51 µs with a 100% probability of interception (POI). Advanced tools such as frequency mask triggering (FMT), density, 3D, spectrogram, and power-versus-time (PvT) displays enable multidimensional analysis of complex signals, ideal for interference detection and spectrum monitoring in dynamic 5G environments.
The SHA860A streamlines maintenance with fast single-port measurements of cable loss, return/insertion loss, VSWR, and distance to fault. An optional upgrade adds 1-path, 2-port vector network analyzer functionality, supporting S11/S21 testing, Smith chart visualizations, and a 114 dB dynamic range for accurate amplitude/phase response analysis.
The pulse analysis function has 10,001 measurement points to evaluate power, pulse transitions, and signal characteristics using multiple detection modes (positive/negative peak, sample, average, and conventional).
Beyond base station testing, identifying 5G/LTE coverage in specific areas is crucial. The indoor/outdoor mapping feature allows technicians to locate base stations, track antenna orientation/height, and identify areas of weak coverage or high interference. With data logging, playback, and ±0.01 ppm accuracy after GPS lock, it simplifies network optimization in both indoor and outdoor environments.
IQ Data Acquisition:
The signal and spectrum analyzer with IQ data acquisition functionality is a common signal acquisition tool. Equipped with 1 GB of RAM, a 300 MHz sampling rate, and a 110 MHz bandwidth, the SHA860A offers a powerful combination of specifications, features, and portability for users collecting data in field environments. Users can transmit and store IQ data via USB or LAN for offline analysis, enabling them to reproduce signals and visualize spectral details with unparalleled clarity.
