Keysight Expert Network Analyzers

视频

This video introduces Keysight Expert Benchtop Vector Network Analyzers (VNAs), designed for enhanced network analysis, active device characterization, and complex modulation testing. Building on the passive testing capabilities of Essential VNAs, Expert VNAs add high‑performance active‑device measurements, direct digital synthesis (DDS) sources, and metrology‑grade performance for engineers working across commercial RF, aerospace, defense, and emerging 5G/6G applications. These analyzers support key measurements such as gain compression, harmonic distortion, intermodulation, and phase‑versus‑drive for active components including power amplifiers, LNAs, and single‑stage mixers.

Expert VNAs extend measurement capability across the millimeter‑wave spectrum, offering 5G FR2 coverage and optional frequency extender support up to 250 GHz. Engineers can measure and characterize nonlinear RF behavior, evaluate wideband modulation performance, and analyze vector signals using integrated VSA tools and internal DDS sources. With low‑noise receiver options, 2‑source configurations, and maximum frequencies up to 67 GHz, Expert VNAs provide the versatility required for testing modern RF front ends, converters, antennas, filters, and millimeter‑wave components. Optional software further enables material measurements, pulsed‑RF analysis, device modeling, and expert S‑parameter characterization.
 

Key features include:

  • Active Device Test: Characterize active components such as power amplifiers and mixers with measurements for gain compression, distortion, intermodulation, and phase‑versus‑drive.
  • 5G FR2 Coverage: Support millimeter‑wave spectrum evaluation for high‑frequency, high‑data‑rate wireless systems.
  • Vector Signal Analysis: Measure modulated signals and analyze nonlinear device behavior using up to two internal DDS sources.
  • Sub‑THz Compatibility: Operate up to 67 GHz natively or extend measurements to 250 GHz using frequency extender modules.
     

Expert Benchtop Vector Network Analyzers provide enhanced RF and microwave capability with active‑device measurements, wide frequency options, and expert software tools. Engineers working on nonlinear devices, millimeter‑wave components, and next‑generation wireless systems rely on Expert VNAs for accuracy, flexibility, and deep performance insight.
