Page 29: Command Reference
The common commands are defined in IEEE std. 488.2-1987, and these commands are common for all devices. The SCPI commands are used to control all of the AT520/A520SE's functions. The SCPI commands are tree structured three levels deep. The highest level commands are called the subsystem commands in this manual. - Page 30 AT520/AT520SE/AT520L/AT520M User’s Guide Example: function:range:auto on function Subsystem Command range Level 2 auto Level 3 Parameter The basic rules of the command tree are as follows.
