Signal Distribution and Routing

Preserve Signal Fidelity
Flexible Solutions
Modular / High-Density Designs

VTI's signal switching solutions have revolutionized the automated signal switching marketplace by providing a level of modularity, density, and performance that continues to be unparalleled in the industry.

Accurate Data Demands Precision Switching

Signal switching is at the heart of every automated test system. It is responsible for routing signals of interest between test system instruments and the device under test. The purpose of the testing is to improve product quality. Since switching is effectively an extension of the test instrument, it should be transparent to the overall system.

Switch Systems That Lack Signal Transparency Destroy Signal Integrity

The Signal Switching Leader for 20 years

Our switches are used in testing the most complex products in the world including avionics, missiles, transportation electronics, engines, launch vehicles and radars. VTI switching products employ extensive signal shielding and high-quality relays to ensure that the test system is ‘minimally aware’ of the switch’s presence.

We offer signal switching solutions for:

  • High Fidelity Analog
  • RF
  • Audio
  • Microwave
  • Optical

All of VTI’s signal switching solutions are based on industry standard platforms that have a history of long-term viability. Our SMIPII series of VXI-based products set the standard for the military and aerospace community where high-channel count, high-mix requirements are the norm. Reliability, functionality, and ease of use have resulted in successes with programs such as the F-35 Joint Strike Fighter LM-STAR, the Navy's RT-CASS, US Air Force VDATS and ADTS (B1B) test stations. Our ruggedized SVM series of VME-based switch modules are ideal for flightline testing and any other harsh environment. The EX1200 LXI Class A product line is a scalable architecture that provides the granularity to address small-large channel count applications.
