samples
scan
one or more analog samples taken at the same time, or nearly the same time.
Typically, the number of input samples in a scan is equal to the number of
channels in the input group. For example, one scan, acquires one new
sample from every analog input channel in the group.
SCAN CLK
scan clock signal used to increment to the next channel after each
E/M Series DAQ device analog-to-digital conversion
SCXI
Signal Conditioning eXtensions for Instrumentation
SCXIbus
located in the rear of an SCXI chassis, the SCXIbus is the backplane that
connects modules in the same chassis to each other
