Programmable Gain Instrumentation Amplifier
Plug and Play devices
devices that do not require DIP switches or jumpers to configure
resources on the devices—also called switchless devices
port
(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
posttriggering
the technique used on a DAQ device to acquire a programmed number
of samples after trigger conditions are met
potentiometer
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
ppm
parts per million
precision
the measure of the stability of an instrument and its capability to give
the same measurement over and over again for the same input signal
pretriggering
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
pseudodifferential input
pseudodifferential input channels are all referred to a common ground,
but this ground is not directly connected to the computer ground
