The use of switching systems to route instrumentation and stimulus signals to appropriate test points on a unit under test has a very crucial role to play in most electronics test systems. The sharing of test resources, connection of calibration references, load management, and many other functions are all managed by the switching system, the switching system acts as the interface between the unit under test (UUT) and the test equipment.
LXI instruments range from LXI modules that plug into a chassis to standalone instruments that have dedicated LXI and hardware trigger bus connections. These instruments can be configured to measure many types of variables to precise values.
PXI Express is the fastest data acquisition platform currently available with unmatched bandwidths in excess of 1 GB/s and latencies less than 1 µs.
The first VXIbus specification was introduced to the test and measurement community in 1987 and was initially developed to provide a card-based instrumentation platform for applications that required high density and high performance.
