Some Facts -

Modbus Protocol is a messaging structure developed by Modicon (Schneider Electric) in 1979. It is used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment.

Anritsu Corporation - Test and Measurement

Information network test & measurement for mobile & internet, RF&Microwave solutions, fibre-optic telecommunications and industrial solutions.

Anritsu Corporation - Test and Measurement

Anritsu Corporation is a Japanese company specializing in the test and measurement equipment market. Products include microwave, radio frequency (RF), and optical signal generators, spectrum analyzers, and network analyzers.



The VectorStar family is Anritsu's Premium VNA line, providing the highest overall performance on a modern platform. The 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.

VectorStar Family of RF, µW, mmW VNAs MS4640B Series

The Anritsu MS4640B Vector Network Analyzer offers a new level of performance for device modeling engineers struggling to accurately and reliably characterize 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 maximize throughput without sacrificing accuracy

1931- Anritsu Electric Corporation was established by the merger of Kyoritsu Electric and Annaka Electric
