USB

Universal Serial Bus (USB) interface computer connection

The Universal Serial Bus (USB) interface is a popular digital interface for quick and easy connection of measurement devices to desktop & laptop computers and other digital measurement instrumentation.

A USB connection provides a global standard for the physical electrical connection, communication and powering of digital sensors and measurement instruments. A single cable is used for sending all the read & write commands, and providing a low dc supply voltage.

USB is a popular method for connecting measurement devices together in a research laboratory environment on experimental test rigs, where all test equipment is close by on the same test bench or rig.

The majority of USB measurement devices come with application software which can be installed on a laptop or desktop computer. USB provides the user with a plug & play set-up that can be up and running very quickly without the need for wiring, separate power supplies or signal conditioning instrumentation.
