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 work-stations;
it offers a theoretical maximum transfer rate of 132 Mbytes/s.
programmable function input
devices that do not require DIP switches or jumpers to configure resources
on the devices—also called switchless devices
a communications connection on a computer or a remote controller
the technique used on a DAQ device to acquire a programmed number of
samples after trigger conditions are met
parts per million
the technique used on a DAQ device to keep a continuous buffer filled with
data, so that when the trigger conditions are met, the sample includes the
data leading up to the trigger condition
the inherent uncertainty in digitizing an analog value due to the finite
resolution of the conversion process
a device that maps a variable from a continuous distribution to a discrete
distribution
