Keysight Handheld Signal Analyzers

视频

This video introduces Keysight Handheld Signal Analyzers, rugged and portable instruments designed for comprehensive RF field testing across telecommunications, defense, aerospace, and industrial environments. These analyzers combine spectrum analysis, vector network analysis, power measurements, wideband demodulation, and pulse generation in a compact, battery‑powered platform that supports efficient on‑site validation, troubleshooting, and network characterization. Field engineers can perform over‑the‑air (OTA) testing, interference hunting, cable and antenna verification, and EMF assessments using a single, versatile handheld device.

Building on Keysight’s industry‑leading RF measurement technology, handheld signal analyzers support spectrum analysis with real‑time capabilities, vector network analysis for cable, antenna, and S‑parameter testing, and integrated power measurement tools for channel power and pulsed RF characterization. Wideband support enables LTE, 5G NR, and emerging wireless protocol measurements, while optional GPS receivers, channel scanners, and EMF measurement tools enhance field‑deployment workflows. With compatibility across more than 75 signal analysis and application‑specific measurement tools, these analyzers scale from routine RF validation to advanced modulation analysis and system‑level debugging.
 

Key features include:

  • Spectrum Analysis: Includes real‑time analysis, analog demodulation, gapless IQ capture, and interference‑hunting capabilities for dynamic RF environments.
  • Cable & Antenna Testing: 2‑port VNA enables cable testing, S‑parameter measurements, and TDR‑based diagnostics.
  • Power Measurements: A built‑in power meter provides channel‑power measurements, with support for external USB peak‑power sensors for pulsed RF signals.
  • Signal Generation: Integrated signal generator produces analog‑modulated signals and user‑defined pulse sequences for system stimulation and validation.
  • 5G & LTE Testing: Perform OTA testing for 5G NR and LTE, including EMF measurements, a channel scanner, GPS receiver support, and wideband signal analysis.
     

Handheld Signal Analyzers deliver rugged portability, wide measurement breadth, and extensive software compatibility for RF field engineers. With capabilities spanning spectrum analysis, VNA, power measurement, pulse generation, and 5G/LTE testing, they provide a reliable platform for comprehensive on‑site signal characterization and diagnostics.
