VTI Expands Broadband Microwave Switch Family

VTI Instruments Corporation is pleased to announce the expansion of their broadband RF and microwave signal distribution family with the addition of the EX71HD high-density, modular 26.5 GHz microwave switch.

The EX71HD is designed to address applications that demand maximum performance, flexible design options, and an operating range up to 26.5 GHz. It is ideal for reconfigurable ATE applications where signal integrity must be maintained when routing critical signals between the device(s) under test and instrumentation such as spectrum analyzers, high frequency oscilloscopes, synthesizers, and network analyzers.

"Switch systems that lack signal transparency destroy signal integrity, so why invest in expensive instrumentation and then spend hours processing distorted signals?," said Jon Semancik, VTI's Director of Marketing. "The EX71HD is an ideal broadband test system core enabling high-integrity signal switching between multiple sources and measurement instruments."

A wide range of applications can be easily addressed with SPDT, SP4T, SP6T building blocks configured to meet specific signal routing requirements, such as 6 x 6 matrixes, 1 x 16 multiplexer, and a multitude of other combinations. All switches are front panel "pluggable", and when combined with the built-in relay odometer, facilitate quick field maintenance and service activities. Automatic power up states, path level configurations, and exclude lists simplify programming and optimize system level performance.

Programming is greatly simplified by using the built-in web-based graphical user interface (GUI) to configure unique path level assignments, eliminating time consuming programming and debugging steps. While the open architecture hardware platform and software-based communications interface provides the foundation for a common, corporate-wide solution.
