Chapter 3 System Overview
Signal Routing and Switching
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.
