parts per million
A rugged, open system for modular instrumentation based on CompactPCI,
with special mechanical, electrical, and software features. The PXIbus
standard was originally developed by National Instruments in 1997, and is
now managed by the PXIbus Systems Alliance.
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.

seconds
An instantaneous measurement of a signal, normally using an
analog-to-digital converter in an E Series DAQ device.
The number of samples a system takes over a given time period, usually
expressed in samples per second.
One or more analog or digital input samples. Typically, the number of input
samples in a scan is equal to the number of channels in the input group. For
example, one pulse from the scan clock produces one scan which acquires
one new sample from every analog input channel in the group.
Scan clock signal used to increment the next channel after each E Series
DAQ device analog-to-digital conversion.
