multiplexed mode
an SCXI operating mode in which analog input channels are multiplexed
into one module output so that your cabled DAQ device has access to the
module’s multiplexed output as well as the outputs of all other multiplexed
modules in the chassis
multiplexer
a switching device with multiple inputs that sequentially connects each of
its inputs to its single output, typically at high speeds, in order to measure
several signals with a single analog-to-digital converter
mux
