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.
a measure of signal amplitude; the difference between the highest and
lowest excursions of the signal
programmable function input
a feature in FFT mode that lets you set a threshold to effectively filter out
noise from signal phase information
devices that do not require DIP switches or jumpers to configure resources
on the devices—also called switchless devices
(1) a communications connection on a computer or a remote controller
(2) a digital port, consisting of four or eight lines of digital input and/or
output
the technique used on a DAQ board to acquire a programmed number of
samples after trigger conditions are met
an electrical device the resistance of which can be manually adjusted; used
for manual adjustment of electrical circuits and as a transducer for linear or
rotary position
parts per million
the technique used on a DAQ board 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 transmission of a signal through a computer system
the amount of time required for a signal to pass through a circuit
points
multiple pulses
a form of counter signal generation by which a pulse is outputted when a
counter reaches a certain value
