L
lead resistance
the small resistance of a lead wire. The resistance varies with the lead
length and ambient temperature. If the lead wire carries excitation current,
this varying resistance can cause measurement error.

master-out-slave-in signal
multiplex
to route one of many input signals to a single output
multiplexed mode
an SCXI operating mode in which analog input channels are multiplexed
into one module output so that the cabled E Series DAQ device has access
to the multiplexed output of the module as well as the outputs of all other
multiplexed modules in the chassis
mux
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
