Matrix Switching
A matrix switch connects multiple inputs to multiple outputs and therefore offers
more switching flexibility than a multiplexer. Use a matrix for switching
low-frequency (less than 10 MHz) signals only. A matrix is arranged in rows and
columns. For example, a simple 3x3 matrix could be used to connect three
sources to three test points as shown below.
Any one of the signal sources can be connected to any one of the test inputs. Be
aware that with a matrix, it is possible to connect more than one source at the
same time. It is important to make sure that dangerous or unwanted conditions
are not created by these connections.
