5G NR OTA Measurement (option SHA860-NR)

Accurate assessment of network quality and beam performance is essential during 5G base station deployment. The SHA860A’s 5G NR OTA mode demodulates signals to retrieve critical metrics such as frequency, physical cell ID (PCI), SSB index, frequency offset, and error vector magnitude (EVM) for the SSB segment, all displayed through constellation diagrams. This capability is crucial for fine-tuning 5G Non-Standalone (NSA) setups, ensuring smooth integration between LTE and 5G systems.

LTE TDD/FDD OTA Measurement (option SHA860-LTE)

The LTE OTA testing function delivers detailed demodulation data, including PCI, sector ID, cell group, frequency offset, time delay, sync status, and power levels for PSS, SSS, CRS, and PBCH, along with EVM values and constellation visuals. By evaluating signal integrity, channel behavior, and interference across multiple cells, technicians can apply focused improvements to boost network performance and user satisfaction.

Real-Time Spectrum Analysis (option SHA860-B1A)

Equipped with 110 MHz real-time bandwidth and a processing speed of 300,000 FFTs per second, the SHA860A can detect transient signals as brief as 3.51 µs with 100% Probability of Intercept (POI). It includes advanced analysis tools such as frequency mask triggering (FMT), density plots, 3D views, spectrograms, and Power vs. Time (PvT) displays, enabling in-depth, multi-dimensional examination of complex signals—ideal for interference detection and spectrum analysis in fast-changing 5G environments.
