O
output voltage
compliance
the largest voltage that can be generated across the output of a current
source without the current going out of specification
OUT REF output reference signal
P
ppm parts per million
PXI PCI eXtensions for Instrumentation—an open specification that builds on
the CompactPCI specification by adding instrumentation-specific features
R
RLlead resistance
RMA Return Material Authorization
RSVD reserved bit, pin, or signal
RTD resistance-temperature detector
S
s seconds
S 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
