Configure Channels and Tasks

A

physical channel

is a terminal or pin at which you can measure or

generate an analog or digital signal. A

virtual channel

is a collection of

settings that can include a name, a physical channel, input terminal
connections, the type of measurement or generation, and scaling
information. In Traditional NI-DAQ and earlier versions, configuring
virtual channels is an optional way to record which channels are used for
different measurements. In NI-DAQmx, virtual channels are integral to
every measurement.
