Keysight Vector Network Analyzers

Videos

This video introduces Keysight’s Vector Network Analyzer (VNA) portfolio—Essential, Expert, and Pro benchtop performance grades, as well as Modular and USB form factors—designed to provide precise, high‑performance RF and microwave characterization across a wide range of applications. Keysight VNAs combine exceptional dynamic range, integrated low‑noise receivers, wide analysis bandwidths, and flexible multiport configurations to accelerate insight and ensure accurate, repeatable measurements.

  • Essential benchtop vector network analyzers offer 3 GHz to 18 GHz maximum frequency ranges with 2‑port configurations and 1 source. These instruments provide reliable, high‑throughput network analysis and are ideal for general‑purpose S‑parameter testing. Essential VNA capabilities are also available in compact Modular and USB platforms.

  • Expert benchtop vector network analyzers extend performance with frequencies up to 67 GHz, 2–4 ports, and up to two low‑noise receivers. These analyzers support enhanced analysis for nonlinear device testing, making them suitable for more demanding RF component validation.

  • Pro benchtop vector network analyzers deliver Keysight’s highest performance with up to 4 sources, 2 low‑noise receivers, and frequencies up to 67 GHz. They are engineered for next‑generation design, active device development, and complex characterization beyond traditional S‑parameters. 

  • Modular vector network analyzers, housed in PXIe form factors, support up to 53 GHz, provide up to 2 ports per module, and enable scaling to as many as 50 test ports in a single chassis. With up to 100 dB dynamic range at 50 GHz, they are ideal for large multiport switching systems and automated test environments.

  • USB vector network analyzers extend portability with 2‑, 4‑, and 6‑port configurations up to 53 GHz, connecting directly to a host PC for lightweight, flexible measurements in lab or field applications.

Across all levels, Keysight VNAs feature configurable multiport setups, front‑panel loops, and seamless integration with automated test systems—reducing cabling complexity and improving efficiency. Engineers can characterize linear and nonlinear devices, perform wideband analysis, and access advanced measurement applications through integrated software. 
 
Keysight’s VNA portfolio delivers the accuracy, speed, connectivity, and test depth needed to characterize modern RF systems and components—from basic network analysis to advanced research and active device development.

NA5205A PNA-X Pro Vector Network Analyzer

With the source-per-port PNA-X pro network analyzer, consolidate your design verification process, reduce your test cycle time, and minimize your potential errors. The source-per-port PNA-X pro network analyzer simplifies testing of complex active components, like frequency converters and differential amplifiers, by incorporating up to four ultra-low phase noise and harmonic signal sources, two low-noise receivers, and two combiners in a single setup. This configuration reduces the need for extensive cabling and minimizes signal power losses during high-power testing. The integrated hardware eliminates the necessity for external signal generators and switches, streamlining the test setup.
