A
A
Amperes.
A/D
Analog-to-digital.
absolute accuracy
The maximum difference between the measured value from a data
acquisition device and the true voltage applied to the input, typically
specified as ± voltage.
AC Alternating
current.
ADC
Analog-to-Digital Converter—An electronic device, often an integrated
circuit, that converts an analog voltage to a digital number.
ADE
Application development environment such as LabVIEW,
LabWindows/CVI, Visual Basic, C, and C++.
AI
Analog input.
AI GND
Analog input ground signal.
AI HOLD COMP,
AI HOLD
Scan clock signal used to increment to the next channel after each
E/M Series DAQ device analog-to-digital conversion.
amplification
A type of signal conditioning that improves accuracy in the resulting
digitized signal by increasing signal amplitude relative to noise.
B
bandwidth
The range of frequencies present in a signal, or the range of frequencies to
which a measuring device can respond.
bridge completion
resistors
Fixed-valued resistors used to complete a wheatstone bridge when fewer
than four of the bridge elements are working strain gauges.
Butterworth filter
A lowpass filter whose characteristics are optimized for maximum flatness
in the passband.
C
C
Celsius.
CE
European emissions control standard.
