The SMU4032 is the only mobile USB switch with instrumentation specifications, making it the only mobile USB switch that enables your 6-1/2 or 7-1/2 digit DMM to deliver its full accuracy. Weighing in at less then a pound, and with dimensions of 5'' X 7'' X 1.3'', the SMU4032 is ideal for environments and applications where size, weight, or mobility requirements rule out traditional bench top equipment.

The SM4040 series of high-density PCI plug-in 40 and 20 channel Relay Switching Matrix is designed specifically for use in applications requiring precision signal switching. The small physical size and built-in intelligence of the SM4040 family make them ideal for automated test systems and data acquisition applications. The Switching Matrices are controlled with high-level commands to their on-board controller. This simplifies programming and minimizes the overhead typical with other Switching Cards.

The SM4042 and SM4022 have the same switching functions as the SM4040 and SM4020 but use a proprietary isolated drive method to further reduce noise and other error sources. If you need to switch low-level signals and maintain high integrity, these are the best Switching Cards for the job.
