sense inf our-wireresistance the sense measures the voltage across the resistor
being excitedby the excitation current
settling time the amount of time required for a voltageto reach its final value within
specifiedlimits
sourcei mpedance aparameter of signal sources that reflects current-driving ability of voltage
sources(lower is better) and the voltage-driving ability of current sources
(higher is better)
systemnoise a measure of the amount of noise seen by an analog circuitor anADC when
the analog inputs are grounded
T
temperature
coefficient
thepercentage that a measurement will vary according to temperature. See
thermal drift
thermald rift measurementsthat change as the temperature varies
thermalE MFs thermalelectromotive forces—voltages generated at the junctions of
dissimilar metals that are functions of temperature. Also called
thermoelectric potentials.

transferrate the rate,measured in bytes/s, at which data is moved from source to
destinationafter software initialization and set up operations; the maximum
rateat which the hardware can operate
trigger any event that causes or starts some form of data capture.
U
undersampling sampling at a rate lower than the Nyquist frequency—can cause aliasing
update rate the number of output updates per second
