S/s
samples per second—used to express the rate at which a DAQ board
samples an analog signal
samples an analog signal
stage
in Arb mode, specifies the buffer to be generated, the number of loops on
that buffer, the marker position for that buffer, and the sample count for the
buffer; for DDS mode, specifies the frequency to be generated of the
waveform in the lookup memory and the time for which that frequency has
to be generated

staging list
a buffer that contains linking and looping information for multiple
waveforms; also known as a sequence list or waveform sequence
