SCSI
Small Computer System Interface (bus)
sequence list
See staging list.
shift-keying
frequency shift keying (FSK)
single trigger mode
when the arbitrary waveform generator goes through the staging list only
once
SMB
Sub Miniature Type B connector that features a snap coupling for fast
connection
S/s
samples per second—used to express the rate at which a DAQ board
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
stepped trigger mode
a mode of waveform generation used when you want a trigger to advance
the waveforms specified by the stages in the staging list
SYNC
TTL version of the sine waveform output signal generated by the NI 5401
T
trigger
any event that causes or starts some form of data capture
TTL
transistor-transistor logic
U
update rate
the rate at which a DAC is updated
