PCI-6023E/6024E/6025E User Manual
the input range over which a circuit can handle a common-mode signal
the mathematical average voltage, relative to the computer's ground, of the
signals from a differential input
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
convert signal
a circuit that counts external pulses or clock pulses (timing)
an unwanted signal on one channel due to an input on a different channel
counter
the amount of current a digital or analog output channel is capable of
sourcing or sinking while still operating within voltage range specifications
the ability of a DAQ board to dissipate current for analog or digital output
signals
the ability of a DAQ board to supply current for analog or digital output
signals
digital-to-analog
digital-to-analog converter—an electronic device, often an integrated
circuit, that converts a digital number into a corresponding analog voltage
or current
analog channel 0 output signal
analog channel 1 output signal
data acquisition—(1) collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and inputting them to a
computer for processing; (2) collecting and measuring the same kinds of
electrical signals with A/D and/or DIO boards plugged into a computer, and
possibly generating control signals with D/A and/or DIO boards in the
same computer
