The Siglent SHA861A is a 9 kHz–3.6 GHz handheld spectrum analyzer with -165 dBm/Hz DANL, 110 MHz real-time analysis, and 5G NR/LTE OTA testing. It offers VNA (S11/S21), cable and antenna tests, EMI measurements, and advanced modulation analysis. Rugged and portable with an 8.4" touchscreen, GPS mapping, and 2.5-hour battery for powerful RF fieldwork.

The Siglent SHA861A is a powerful and portable signal analyzer designed for modern wireless communication and general RF field analysis. Offering laboratory-grade performance in a compact, rugged form factor, it is ideal for both field engineers and RF specialists who demand versatility and precision.

With a frequency range from 9 kHz to 3.6 GHz, the SHA861A covers a wide array of wireless communication bands, making it perfectly suited for emerging technologies like 5G NR and LTE. Its displayed average noise level (DANL) reaches an impressive -165 dBm/Hz, ensuring sensitive signal detection even in noisy environments.

Packed with a host of advanced functions, the SHA861A enables deep analysis of modern signals:

Real-Time Spectrum Analysis with 110 MHz bandwidth (option), offering a fast 3.51 µs 100% POI for capturing even the shortest transients.
5G NR and LTE OTA Testing, supporting multi-PCI, multi-beam analysis, constellation diagrams, and EVM measurements.
Comprehensive Modulation Analysis (AM/FM/PM for analog, ASK/FSK/PSK/MSK/QAM for digital).
Field Strength Measurements, EMI pre-compliance testing, and cable and antenna diagnostics using Distance-To-Fault (DTF) and TDR capabilities.
Integrated Vector Network Analysis (S11/S21) and independent CW Source up to 3.6 GHz.
Rugged portability with an 8.4-inch multi-touch screen, 2.5-hour battery life, and a compact 3.2 kg weight.

In short, the SHA861A offers unparalleled measurement versatility in a field-friendly package, ready to tackle today's RF challenges.

5G NR OTA Measurement

During 5G base station deployment, the SHA860A’s 5G NR OTA mode demodulates signals to measure PCI, SSB index, frequency error, and EVM, displayed in constellation diagrams. This ensures optimal 5G NSA performance and smooth LTE-5G coordination.

Real-Time Spectrum Analysis

The SHA860A captures signals as short as 3.51 µs with 110 MHz real-time bandwidth and 300,000 FFT/s. Features like FMT, Density, 3D, Spectrogram, and PvT displays enable advanced signal analysis for interference hunting and 5G spectrum monitoring.
