Communicating with your instrument involves sending and receiving commands, settings, responses, and data. The level of communication depends on the type of instrument object you use.
To communicate through the interface object, you need to send
instrument commands, and you receive information as the instrument
sends it. Therefore, you have to know the syntax specific to the instrument
itself. For example, if the instrument requires the command
initiate its action, then that is exactly the command that must be
sent to the interface object.
To communicate through a device object, you access object properties
get commands, and you execute driver
functions with the
invoke command for a device object employs
methods and arguments defined by the instrument driver. So using device
objects does not require you to use instrument-specific commands and
