DAQPad-6507/6508 User Manual
triggering that occurs at an unintended time
a data transfer in which the data bytes are transferred from the source to the
controller, and then from the controller to the target
first-in-first-out
signal sources with voltage signals that are not connected to an absolute
reference or system ground. Also called nonreferenced signal sources.
Some common example of floating signal sources are batteries,
transformers, or thermocouples.
a type of high-performance data transfer in which the data bytes pass
directly from the source to the target without being transferred to the
controller
feet
ground
General Purpose Interface bus, synonymous with HP-IB. The standard bus
used for controlling electronic instruments with a computer. Also called
IEEE 488 bus because it is defined by ANSI/IEEE Standards 488-1978,
488.1-1987, and 488.2-1987.
level of random vibration
the location where two or more grounds (such as digital ground, analog
output ground, analog input ground, and so on), are connected or tied
together
See referenced single-ended measurement system.
