Handheld Signal Analyzer Siglent SHA861A 3.6GHz

Features SHA861A

5G NR OTA Measurement

During 5G base station deployment, operators require precise validation of network quality and beam performance. The SHA860A’s 5G NR OTA mode demodulates signals to extract key parameters, including frequency, physical cell identity (PCI), SSB index, frequency error, and error vector magnitude (EVM) for the SSB portion, visualized via constellation diagrams. This functionality is vital for optimizing 5G Non-Standalone (NSA) deployments, ensuring seamless coordination between LTE and 5G networks. 

LTE TDD/FDD OTA Measurement

The LTE OTA testing feature provides comprehensive demodulation metrics such as PCI, sector ID, cell group, frequency error, time offset, synchronization status, and power levels (PSS/SSS/CRS/PBCH), alongside EVM measurements and constellation diagrams. By analyzing signal quality, channel performance, and interference across multiple cells, technicians can implement targeted strategies to enhance network efficiency and user experience. 

Real-Time Spectrum Analysis

With a 110 MHz real-time bandwidth and 300,000 FFT/s processing speed, the SHA860A captures transient signals as short as 3.51 µs at 100% Probability of Intercept (POI). Advanced tools like frequency mask triggering (FMT), Density, 3D, Spectrogram, and Power vs. Time (PvT) displays enable multi-dimensional analysis of complex signals, ideal for interference hunting and spectrum monitoring in dynamic 5G environments. 

Cable and Antenna Test

Component faults compromise base station performance, leading to coverage gaps and signal strength degradation. The SHA860A streamlines maintenance with rapid single-port cable loss, return/insertion loss, VSWR, and distance-to-fault measurements. An optional upgrade adds 1-Path 2-Port vector network analyzer functionality, supporting S11/S21 testing, Smith chart displays, and a remarkable 114 dB dynamic range for precise amplitude/phase response analysis. 

Pulse Profile Analysis

The pulse analysis function featuring 10,001 measurement points to evaluate power, pulse transitions, and signal characteristics using multiple detection modes (positive/negative peak, sample, average, and conventional). This ensures rigorous validation of RF device performance in real-world conditions. 

IQ Data Acquisition

Signal and spectrum analyzer with IQ data acquisition function is a common signal acquisition tool. Equipped with 1 GB RAM, 300 MHz sample rate, and 110 MHz bandwidth, the SHA860A provides a powerful combination of specifications, functions and portability for users collecting data in the field environment. Users can transmit and store IQ data via USB or LAN for offline analysis, so as to reproduce signals and visualize spectrum details with unmatched clarity. 

Indoor/Outdoor Mapping

Beyond base station testing, identifying 5G/LTE coverage in specific areas is crucial. The indoor/outdoor mapping feature enables technicians to locate base stations, track antenna orientation/height, and identify weak coverage or high-interference zones. With data logging, playback, and ±0.01 ppm accuracy post-GPS lock, it simplifies network optimization in both indoor and outdoor environments.
