Anritsu MS4640B Series

VectorStar Family of RF, µW, mmW VNAs MS4640B Series


The VectorStar™ family is Anritsu’s Premium VNA line, providing the highest overall performance on a modern platform. The Anritsu MS4640B VectorStar VNA offers the broadest coverage in a single instrument, 70 kHz to 70 GHz. The additional two decades at the low end are even more impressive than the guaranteed 70 GHz coverage on the high end.

PulseView™, when combined with the innovative IF digitising option, offers industry-leading 2.5 ns pulse resolution and 100 dB dynamic range with no compromises or trade-offs due to varying duty cycles. PulseView provides real time display of pulse measurements while dynamically modifying pulse parameters for immediate design validation.

DifferentialView™, when combined with the dual internal source option, offers real time display analysis of differential devices, drivers, and components while actively modifying phase and magnitude relationships of the internal dual sources.

The noise figure option is based on a cold source technique for improved noise figure measurement accuracy. VectorStar is the only VNA platform capable of measuring noise figure from 70 kHz to 125 GHz and available with an optimised noise receiver for measurements from 30 GHz to 125 GHz.

For broadband applications, the Anritsu ME7838A Series offers superior performance and coverage spanning a range from 70 kHz to 110 GHz in a single 1 mm coaxial test port. The Anritsu developed Non-linear Transmission Line mmWave module is compact while providing high performance up to 125 GHz.

The Anritsu MS4640B Vector Network Analser offers a new level of performance for device modelling engineers struggling to accurately and reliably characterise their devices, for R&D engineers pushing the last fraction of a dB out of their state-of-the-art designs, and for the manufacturing engineer trying to maximise throughput without sacrificing accuracy. Backed by a 3-year warranty and the most responsive sales support team, the Anritsu MS4640B is the VNA of choice for the discerning engineer.
