7 Remote Control Commands

In the following, all remote-control commands will be presented in detail with their param-
eters and the ranges of numerical values.

For an introduction to remote control and the status registers, refer to

chapter 6, "Remote

Control Basics"

7.1 Common Commands

Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These com-
mands have the same effect and are employed in the same way on different devices.
The headers of these commands consist of "*" followed by three letters. Many common
commands are related to the Status Reporting System.

Available common commands:
