I'm doing a presentation about NI PXI and such test equipment for school.
And I am explaining what the multiplexer and matrix modules can be used for.
The multiplexer is simple: Connect, for example, all voltage measurement points to the multiplexer inputs, and a DMM to the output, and cycle through them in order and acquire measurements.
But what exactly is the matrix used for? I can't figure out what the advantage of this one is.
