the manipulation of signals to prepare them for digitizing
performing frequency division on an external signal
single in-line memory module
SI counter clock signal
a type of miniature coaxial signal connector
a programmed event that triggers an event such as data acquisition
a method of triggering in which you simulate an analog trigger using
software. Also called conditional retrieval.
a parameter of signal sources that reflects current-driving ability of voltage
sources (lower is better) and the voltage-driving ability of current sources
(higher is better)
an counter input pin where the counter counts the signal transitions
single-pole double throw—a property of a switch in which one terminal can
be connected to one of two other terminals
simultaneous sampling—a property of a system in which each input or
output channel is digitized or updated at the same instant
samples per second—used to express the rate at which a DAQ board
samples an analog signal
start scan signal
strobe input signal
system timing controller
a device whose logical address cannot be set through software; that is, it is
not dynamically configurable
devices that do not require dip switches or jumpers to configure resources
on the devices—also called Plug and Play devices
(1) hardware—a property of an event that is synchronized to a reference
clock (2) software—a property of a function that begins an operation and
returns only when the operation is complete
