an undesirable electrical signal—noise comes from external sources such as
the AC power line, motors, generators, transformers, fluorescent lights,
soldering irons, CRT displays, computers, electrical storms, welders, radio
transmitters, and internal sources such as semiconductors, resistors, and
capacitors. Noise corrupts signals you are trying to send or receive.
(R = V/I)—the relationship of voltage to current in a resistance
the device memory. Onboard memory is distinct from computer memory.
amperages above the maximum power level specified for a device
a segment of the input range of an instrument outside of the normal
measuring range. Measurements can still be made, usually with a
degradation in specifications.
Peripheral Component Interconnect—a high-performance expansion bus
architecture originally developed by Intel to replace ISA and EISA; it is
achieving widespread acceptance as a standard for PCs and workstations
and offers a theoretical maximum transfer rate of 132 Mbytes/s
the absolute maximum or minimum amplitude of a signal (AC + DC)
Programmable Function Input
phase-locked loop—an electronic circuit that controls an oscillator so that
it maintains a constant phase angle relative to a reference signal
PCI eXtensions for Instrumentation—PXI is an open specification that
builds on the CompactPCI specification by adding instrumentation-specific
