H
hysteresis
Lag between making a change and the effect of the change.
I
interchannel delay
Amount of time that passes between sampling consecutive channels. The
interchannel delay must be short enough to allow sampling of all the
channels in the channel list, within the scan interval. The greater the
interchannel delay, the more time the PGIA is allowed to settle before the
next channel is sampled. The interchannel delay is regulated by the
AI CONV signal.
L
LED
Light-Emitting Diode—a semiconductor light source.
M
m
Meter.
measurement device
DAQ devices such as the E Series multifunction I/O (MIO) devices, SCXI
signal conditioning modules, and switch modules.
module
A board assembly and its associated mechanical parts, front panel, optional
shields, and so on. A module contains everything required to occupy one or
more slots in a mainframe. SCXI and PXI devices are modules.
N
NI
National Instruments.
NI-DAQ
Driver software included with all NI measurement devices. NI-DAQ is an
extensive library of VIs and functions you can call from an application
development environment (ADE), such as LabVIEW, to program all the
features of an NI measurement device, such as configuring, acquiring and
generating data from, and sending data to the device. Includes two NI-DAQ
drivers—Traditional NI-DAQ (Legacy) and NI-DAQmx—each with its
own API, hardware configuration, and software configuration.
