measurement
The quantitative determination of a physical characteristic. In practice,
measurement is the conversion of a physical quantity or observation to a
domain where a human being or computer can determine the value.

MIO
Multifunction I/O—DAQ module. Designates a family of data acquisition
products that have multiple analog input channels, digital I/O channels,
timing, and optionally, analog output channels. An MIO product can be
considered a miniature mixed signal tester, due to its broad range of signal
types and flexibility. Also known as multifunction DAQ.
