conditional retrieval A method of triggering in which you to simulate an analog trigger using
software.
Also called
software triggering.
configuration utility Refers to NI-DAQ on the Macintosh,
nicfg16.exe
on Windows 3.1, and
nidaqcfg.exe
on Windows 95/NT.
conversion device Device that transforms a signal from one form to another. For example,
analog-to-digital converters (ADCs) for analog input, digital-to-analog
converters (DACs) for analog output, digital input or output ports, and
counter/timers are conversion devices.
counter.llb
A LabVIEW DAQ library containing VIs that count the rising and falling
edges of TTL signals, generate TTL pulses, and measure the frequency and
period of TTL signals.
counter/timer group A collection of counter/timer channels. You can use this type of group for
simultaneous operation of multiple counter/timers.
coupling The manner in which a signal is connected from one location to another.
D
D/A Digital-to-analog.
DAC Digital-to-analog converter. An electronic device, often an integrated
circuit, that converts a digital number into a corresponding analog voltage
or current.
DAQ Channel Wizard Utility that guides you through naming and configuring your DAQ analog
and digital channels.
DAQ Solution Wizard Utility that guides you through specifying your DAQ application, from
which it provides a custom DAQ solution.
data acquisition Process of acquiring data, typically from A/D or digital input plug-in
boards.
data flow Programming system consisting of executable nodes in which nodes
execute only when they have received all required input data and produce
output automatically when they have executed. LabVIEW is a dataflow
system.
default input The default value of a front panel control.
