4Language DictionaryIntroductionThis section gives the syntax and parameters for all the IEEE 488.2 SCPI subsystem and commoncommands used by the electronic loads. It is assumed that you are familiar with the material in chapter 2"Introduction to Programming". Because the SCPI syntax remains the same for all programminglanguages, the examples given for each command are generic.Syntax Forms Syntax definitions use the long form, but only short form headers (or "keywords")appear in the examples. Use the long form to help make your program self-documenting.Parameters Most commands require a parameter and all queries will return a parameter. Therange for a parameter may vary according to the model of electronic load. Parametersfor all models are listed in the Specifications table in the User’s Guide.Channel If a command only applies to individual channels of a mainframe, the entry ChannelSelectable will appear in the command description.RelatedCommandsWhere appropriate, related commands or queries are included. These are listedbecause they are either directly related by function, or because reading about themwill clarify or enhance your understanding of the original command or query.Order ofPresentationThe dictionary is organized as follows: Subsystem commands, arranged by subsystem IEEE 488.2 common commandsSubsystem CommandsSubsystem commands are specific to functions. They can be a single command or a group of commands.The groups are comprised of commands that extend one or more levels below the root. The descriptionof common commands follows the description of the subsystem commands.The subsystem command groups are arranged according to function: Calibration, Channel, Input, List,Measurement, Port, Status, System, Transient, and Trigger. Commands under each function are groupedalphabetically under the subsystem. Commands followed by a question mark (?) take only the queryform. When commands take both the command and query form, this is noted in the syntax descriptions.Appendix A lists all subsystem commands in alphabetical order.55
