Matrix Modules
A matrix switch is the most versatile type of system switching. Any input
can be connected to any output, individually or in combination. This
helps minimize the need for complex wiring, and can simplify the DUT
interface. In addition, a matrix module can be used in conjunction with
other modules to provide a wide variety of switching combinations. A
matrix is arranged in rows and columns and a simple 4 x 4 matrix switch
is shown below.
