Light-Emitting Diode—A semiconductor light source.
A filter that passes signals below a cutoff frequency while blocking signals
above that frequency.
Least Significant Bit.
Meter.
An architecture for instrumentation-class, multichannel data acquisition
devices based on the earlier E Series architecture with added new features.
The quantitative determination of a physical characteristic. In practice,
measurement is the conversion of a physical quantity or observation to a
domain where a human being or computer can determine the value.
DAQ devices, such as the M Series multifunction I/O (MIO) devices, SCXI
signal conditioning modules, and switch modules.
Megahertz—A unit of frequency; 1 MHz = 10
The numerical prefix designating 10
Multifunction I/O—DAQ module. Designates a family of data acquisition
products that have multiple analog input channels, digital I/O channels,
timing, and optionally, analog output channels. An MIO product can be
considered a miniature mixed signal tester, due to its broad range of signal
types and flexibility. Also known as multifunction DAQ.
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.
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.
