Instrument Driver Communication

Instrument communication 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.

Topics

Creating and Connecting Device Objects

Includes the general procedure for the creation and use of device objects.

Communicating with Instruments

Configuring and exchanging data through device objects.

Device Groups

Obtaining and using group device properties.

Device Objects

Device objects allow you to configure and query an instrument without knowledge of its command set. The low-level communication is performed through a MATLAB^® instrument driver.
