Introduction to GPIB Programming

Sending Commands

Sending Commands

Commands are sent over the GPIB via a controller's language system, such as IBASIC, QuickBASIC or C. The keywords used by a controller to send GPIB commands vary among systems. When determining the correct keywords to use, keep in mind that there are two different kinds of GPIB commands:

• Bus management commands, which control the GPIB interface.

• Device commands, which control analyzer functions.

Language systems usually deal differently with these two kinds of GPIB commands. For example, HP BASIC uses a unique keyword to send each bus management command, but always uses the keyword OUTPUT to send device commands.

The following example shows how to send a typical device command:

OUTPUT 716;"CALCULATE:MARKER:MAXIMUM"

This sends the command CALCULATE:MARKER:MAXIMUM to the GPIB device at address 716. If the device is an analyzer, the command instructs the analyzer to set a marker to the maximum point on the data trace.
