Instrument Driver Communication

Communicate with instruments using instrument drivers

You need to create an interface object, for example gpib or i2c, to communicate with instruments, as described in many of the sections of the documentation. You can also create a device object that allows you to configure and query an instrument without knowledge of its command set. See Creating and Connecting Device Objects for more information about using device objects.
