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.
Test 1 Test 2 Test 3
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.
