a property of an event or system in which data is processed as it is acquired
instead of being accumulated and processed at a later time
a measure in LSB of the linearity of an ADC. It includes all non-linearity
and quantization errors. It does not include offset and gain errors of the
circuitry feeding the ADC.
the smallest signal increment that can be detected by a measurement
system. Resolution can be expressed in bits, in proportions, or in percent of
full scale. For example, a system has 12-bit resolution, one part in 4,096
resolution, and 0.0244% of full scale.
a technique whereby a device is signaled not to use its local memory while
the memory is in use from the bus
an acknowledge by a destination that signifies that the cycle did not
complete and should be repeated
a flat cable in which the conductors are side by side
the difference in time between the 10% and 90% points of a system's step
response
root mean square—the square root of the average value of the square of the
instantaneous signal amplitude; a measure of signal amplitude
read-only memory

real-time system integration bus—the National Instruments timing bus that
connects DAQ boards directly, by means of connectors on top of the boards,
for precise synchronization of functions
