VTI Instruments - SMX-3xxx product family of Multiplexers
The SMX-3xxx product family includes the SMX-3001 through SMX-3007 and SMX-3276 through SMX-3280 multiplexers.
The VTI SMX-3xxx Series of multiplexers deliver exceptional performance and reliability by implementing extensive signal path shielding and isolation. Available models with software configurable switch subsystems increase flexibility and help control costs by allowing a single module to be used for different testing requirements. Embedded virtual schematic control further simplifies setup and debugging, allowing all relays to be engaged independent of application software.
Ideally suited for medium-to-high density automated test systems (ATE), the SMX-3xxx Series provides uncompromised measurement integrity ideal for the most demanding aerospace, defense and automotive applications.
