Description: The VectorStar? series is Anritsu's advanced vector network analyzer lineup, delivering outstanding overall performance on a modern operating platform. The MS4640B VectorStar vector network analyzer provides the widest frequency coverage from 70 kHz to 70 GHz in a single instrument. While the maximum frequency of 70 GHz is impressive, the additional two decades at the low-frequency end are even more exciting.

IMDView? offers a flexible menu bar that displays real-time measurements when modifying key IMD parameters. The internal combiner option enables single-connection testing of active devices, allowing automatic switching between S-parameter and IMD measurements without reconnecting the DUT.

The PulseView? pulse measurement capability, combined with innovative IF digitization options, delivers industry-leading 2.5 ns pulse resolution and 100 dB dynamic range, requiring no compromise or performance trade-offs for different duty cycles. PulseView provides real-time display of pulse measurements and allows dynamic modification of pulse parameters to promptly validate design specifications.

The DifferentialView? differential option, paired with the internal dual-source feature, enables real-time analysis of differential devices, components, and assemblies while automatically adjusting the phase and amplitude relationship of the internal dual sources.

The noise figure measurement option, based on cold-source technology, enhances noise figure measurement accuracy. VectorStar is the only vector network analyzer capable of measuring noise figure from 70 kHz to 125 GHz, equipped with optimized noise receivers for measurements from 30 GHz to 125 GHz. Additionally, VectorStar is the only VNA that offers a Differential Noise Figure option for characterizing the noise figure of differential devices.

In broadband applications, the ME7838 series delivers exceptional performance and frequency coverage spanning 70 kHz to 110 GHz, 125 GHz, and 145 GHz through a single coaxial test port. Anritsu's mmWave modules, developed using nonlinear transmission line technology, feature a compact design while providing high performance up to 145 GHz.

The Anritsu MS4640B vector network analyzer offers a higher level of performance, assisting device modeling engineers in achieving accurate and reliable device modeling; helping R&D engineers maximize their product design dynamic range to develop state-of-the-art equipment; and enabling manufacturing engineers to maximize production test efficiency while ensuring precision. With a standard 3-year warranty and responsive sales support, the MS4640B vector network analyzer is a smart choice for engineers.
