Individual Switch System Components

icon
Modules

Explore general-purpose relays, multiplexers, and matrix switch modules in both the SCXI and PXI platforms for increased test throughput and measurement flexibility.

icon
Signal Connectivity

Use terminal blocks, cables, discrete connectors, or mass interconnect solutions to connect signals from instruments to units under test.

icon
Matrix/Multiplexer/Chassis Expansion

Expand many NI matrix and multiplexers with expansion plugs and cables that eliminate the need for custom wiring.

icon
Controllers

NI PXI, PXI/CompactPCI, and USB switch controllers provide complete control of SCXI-based switching systems.

icon
USB Switching

Take advantage of USB to reduce switch system setup time. USB Switch Mainframes eliminate most system configuration tasks and work with all NI SCXI switch modules. USB communication adapters also are available to help you upgrade legacy SCXI switch systems to USB.

icon
NI Switch Executive and Driver Software

Accelerate your switch system development and simplify your switch system maintenance using NI Switch Executive or high-performance NI switch driver software.
