Communicating with Your Instrument
Interface Objects and Instrument Commands
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.
Text commands and binary data are sent directly to the instrument
and received from the instrument with such functions as
Device Objects and Instrument Drivers
To communicate through a device object, you access object properties with the
get commands, and you execute
driver functions with the
invoke command. 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 syntax.
