EX72SF


DC-40 GHz High Performance Modular Microwave Switch (2U)

  • Combine up to 6 SPDT and 6 multiport high-perfomance building blocks in 2U footprint
  • Extended life and self-terminating options provide maximum design flexibility
  • Embedded web interface provides interactive utility to monitor and control relays from anywhere in the world
  • Flexible API supports IVI and Linux development environments minimizing software investment
  • LXI Class A Trigger Event implementation provides seamless test synchronization with external devices
Overview

The EX72SF is a high-density microwave switching platform that is designed to address applications that demand maximum performance, flexible design options, and an operating range to either 20 GHz, 26.5 GHz or 40 GHz. Configuration options include self-termination of unused ports and an expected lifetime of > 5 million cycles. Any combination of up to twelve latching building blocks can be housed in a single 2U rack LXI Class A enclosure. Building block topologies include SPDT, SP4T, SP6T, and transfer switches, as well as a 6-line pass-through adapter and 32-bit TTL I/O bus that can be used to drive external circuitry.

To configure your switch simply follow these three steps

Step 1 - Start with the EX72SF base unit. It holds up to twelve microwave building blocks in two rack U (3.5") height
Step 2 - Select up to six SPDT and six multiport switches
Step 3 - Contact VTI Instruments for price and delivery

Intuitive command and control

The EX72SF software architecture has been developed to allow it to be easily integrated with other GPIB, PXI, VXI, or LXI instruments. The software drivers are based on the IVI industry standard and can be used within virtually any application development environment in addition to Windows and Linux operating systems. An intuitive graphical web-based interface provides the necessary tools for controlling and monitoring an EX72SF through local or remote access using familiar web browsers.



The EX72SF leverages the EX7000-OEM feature set and provides users with tools that can be used to enhance the efficiency of their application, such as scan lists, exclude lists, programmable MBB and BBM, pre-defined configuration storage, LXI Class A Trigger Events and IEEE-1588 synchronization and triggering, and TTL I/O control of other devices.

Measurement integrity, repeatability and long life

The goal of a system engineer is to make a switching interface as invisible as possible to the rest of the system in order to maximize the integrity of the signals passing through it. The EX72SF uses relays that employ superior design technology and deliver unmatched isolation and minimal crosstalk resulting in a high-degree of confidence in measurement accuracy. However, the quality of a system design also depends on its ability to deliver repeatable measurement performance. Repeatability specifies the measure of change that occurs in insertion loss over the rated life of the switch, and systems that utilize relays with performance that drifts over time drive the need for costly recalibration of the system. EX72SF switches guarantee an industry-leading repeatability of insertion loss within a maximum of 0.03 dB throughout their rated lifetime to provide consistent

Measurement performance

The EX72SF platform further drives down the total cost of ownership by providing operating life of > 2 million cycles. Many automated test systems can execute thousands of cycles per day on a single relay, and for demanding applications such as these, extended life (EL) options are available to extend the operating life to > 5 million cycles. With a powerful combination of economical price and outstanding performance, the EX72SF is capable of handling a wide array of application spaces ranging from aerospace and defense to commercial wireless products.

Patented relay technology

The EX72SF relays employ a unique design that ensure highly repeatable closures over time. The center conductor profiles are designed with a spherical mating surface that produces a wiping action as the jumper contact mates with the center conductor. The wiping action removes debris that forms between the contacts of electro-mechanical relays and causes measurement instability. The result is a higher degree of confidence in repeatable data throughout the life of the product.
