National Instruments Corporation G-5 AT-MIO-16X User Manual
common-mode range the input range over which a circuit can handle a common-mode signal
common-mode signal the mathematical average voltage, relative to the computer’s ground, of
the signals from a differential input
common-mode voltage any voltage present at the instrumentation amplifier inputs with respect
to amplifier ground
compensation range the range of a parameter for which compensating adjustment can be
made
conditional retrieval a method of triggering in which you simulate an analog trigger using
software. Also called software triggering.
conversion device device that transforms a signal from one form to another. For example,
analog-to-digital converters (ADCs) for analog input, digital-to-analog
converters (DACs) for analog output, digital input or output ports, and
counter/timers are conversion devices.
conversion time the time required, in an analog input or output system, from the moment
a channel is interrogated (such as with a read instruction) to the moment
that accurate data is available
counter/timer a circuit that counts external pulses or clock pulses (timing)
coupling the manner in which a signal is connected from one location to another
CPU central processing unit
crosstalk an unwanted signal on one channel due to an input on a different
channel
current drive capability the amount of current a digital or analog output channel is capable of
sourcing or sinking while still operating within voltage range
specifications
current sinking the ability of a DAQ board to dissipate current for analog or digital
output signals
current sourcing the ability of a DAQ board to supply current for analog or digital output
