3.13.3 SCPI SUBSYSTEM COMMAND/QUERY STRUCTURE
Subsystem commands/queries are related to specific electronic load functions (such as setting
voltage, current limit, etc.) Figure 3-3 is a tree diagram illustrating the structure of SCPI subsys-
tem commands used in the EL Series Electronic Load with the “root” at the left side, and specific
commands forming the branches. The following paragraphs introduce the subsystems; subsys-
tem commands are defined and explained in Appendix B.
3.13.3.1 DIAGNOSTIC SUBSYSTEM
This subsystem is used to print the SCPI command set.
TABLE 3-2. REMOTE OPERATION COMMAND SUMMARY
