MITE MXI Interface To Everything—A custom ASIC designed by National
Instruments that implements the PCI bus interface. The MITE supports bus
mastering for high-speed data transfers over the PCI bus.
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.
monotonicity A characteristic of a DAC in which the analog output always increases as
the values of the digital code input to it increase.
multichannel Pertaining to a radio-communication system that operates on more than one
channel at the same time. The individual channels might contain identical
information, or they might contain different signals.
multifunction DAQ See MIO.
multiplex To assign more than one signal to a channel. See also mux.
mux Multiplexer—A set of semiconductor or electromechanical switches
arranged to select one of many inputs to a single output. The majority of
DAQ cards have a multiplexer on the input, which permits the selection of
one of many channels at a time.
A switching device with multiple inputs that sequentially connects each of
its inputs to its output, typically at high speeds, in order to measure several
signals with a single analog input channel.

NI-DAQ The driver software needed to use National Instruments DAQ devices and
SCXI components. Some devices use Traditional NI-DAQ (Legacy); others
use NI-DAQmx.
NI-DAQmx The latest NI-DAQ driver with new VIs, functions, and development tools
for controlling measurement devices. The advantages of NI-DAQmx over
earlier versions of NI-DAQ include the DAQ Assistant for configuring
channels and measurement tasks for your device for use in LabVIEW,
LabWindows/CVI, and Measurement Studio; increased performance such
as faster single-point analog I/O; and a simpler API for creating DAQ
applications using fewer functions and VIs than earlier versions of NI-
DAQ.
