Institute of Electrical and Electronics Engineers
the shortened notation for ANSI/IEEE Standards 488-1978, 488.1-1987,
and 488.2-1987. See also GPIB.
a type of digital acquisition/generation where LabVIEW updates the digital
lines or port states immediately or returns the digital value of an input line.
Also called nonlatched digital I/O.
inches
standardized digital communications networks used in industrial
automation applications; they often replace vendor-proprietary networks so
that devices from different vendors can communicate in control systems
integral nonlinearity—a measure in LSB of the worst-case deviation from
the ideal A/D or D/A transfer characteristic of the analog I/O circuitry
the current that flows into the inputs of a circuit
the measured resistance and capacitance between the input terminals of a
circuit
the difference in the input bias currents of the two inputs of an
instrumentation amplifier
a set of high-level software functions that controls a specific GPIB, VXI, or
RS-232 programmable instrument or a specific plug-in DAQ board.
Instrument drivers are available in several forms, ranging from a function
callable language to a virtual instrument (VI) in LabVIEW.
a circuit whose output voltage with respect to ground is proportional to the
difference between the voltages at its two inputs
interrupt enable bit for Port A output interrupts
interrupt enable bit for Port A input interrupts
interrupt enable bit for Port A
interrupt enable bit for Port B
a control action that eliminates the offset inherent in proportional control
