® Remote control commands R&S Common commands 13.2 Common commands Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These commands have the same effect and are employed in the same way on different devi- ces. The headers of these commands consist of "*" followed by three letters. Many common commands are related to the Status Reporting System.
