Creating Instrument Objects
Overview
Instrument objects are the toolbox components
you use to access your instrument. They provide a gateway to the functionality
of your instrument and allow you to control the behavior of your application.
The Instrument Control Toolbox software supports two types of instrument
objects:
Interface objects — Interface objects are associated
with a specific interface standard such as GPIB or VISA. They allow
you to communicate with any instrument connected to the interface.
Device objects — Device objects are associated
with a MATLAB instrument driver. They allow you to communicate
with your instrument using properties and functions defined in the
driver for a specific instrument model.

Interface Objects
An interface object represents a channel of communication. For
example, an interface object might represent a device at address 4
on the GPIB, even though there is nothing specific about what kind
of instrument this may be.
To create an instrument object, you call the constructor for
the type of interface (gpib, serial, tcpip, udp, or visa),
and provide appropriate interface information, such as address for
GPIB, remote host for TCP/IP, or port number for serial.
For detailed information on interface objects and how to create
and use them, see Using Interface Objects.

Device Objects
A device object represents an instrument rather than an interface.
As part of that representation, a device object must also be aware
of the instrument driver.
You create a device object with the icdevice function.
A device object requires a MATLAB instrument driver and some
form of instrument interface, which can be an interface object, a
VISA resource name, or an interface implied in an IVI configuration.
For detailed information on device objects and how to create
and use them, see Using Device Objects.
