Matrix 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.
