Multiplexers are available in several types:
Multiplexer type
One-wire (single-ended)
Two-wire
Four-wire
RF Signal
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 3×3 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 make sure that dangerous or unwanted conditions are not created by these connections.
Form C (SPDT) switching
The DAQM903A contains 20 Form C switches (also called single-pole, double-throw). You can use Form C switches
to route signals but they are typically used to control external devices.
