Signal Routing and Multiplexing
When used stand-alone for signal routing (not scanning or connected to
the internal DMM), multiple channels on the 34901A and 34902A
multiplexers can be closed at the same time. You must be careful that
this does not create a hazardous condition (for example, connecting two
power sources together).
Note that a multiplexer is not directional. For example, you can use a
multiplexer with a source (such as a DAC) to connect a single source to
multiple test points as shown below.
