Data/Address
data acquisition—(1) collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and processing the
measurement data using a computer; (2) collecting and measuring the same
kinds of electrical signals with A/D and/or DIO devices plugged into a
computer, and possibly generating control signals with D/A and/or DIO
devices in the same computer
a data acquisition device. Examples are E/M Series data acquisition devices
the data acquisition device data/address line signal used to indicate whether
the SER DAT IN pulse train transmitted to the SCXI chassis contains data
or address information
a plug-in data acquisition device, module, card, or pad that can contain
multiple channels and conversion devices. SCXI modules are distinct from
devices, with the exception of the SCXI-1200, which is a hybrid.
