Be ready for tomorrow—today

RF requirements keep growing while timelines keep shrinking. To help ease the technical and business pressures, the right test solution provides continuity in measurements and longevity in capability. In the evolution of modular RF test solutions, the Keysight PXI VSA is the next logical step in signal analysis. With raw hardware speed and X-Series measurement applications, it delivers proven results—faster. From fully modular hardware to software leverage to worldwide support, the PXI VSA is the low-risk way to manage change and be ready for tomorrow—today

A typical M9391A configuration includes four individual PXIe modules – M9300A frequency reference, M9301A synthesizer, M9214A Digitizer and M9350A Downconverter. It can be combined with the M9381A Vector Signal Generator for a fast, compact RF component test solution.
