Common Commands

Common commands begin with an * and consist of three letters (command) or three letters and a ?
(query). They are defined by the IEEE 488.2 standard to perform common interface functions. Common
commands and queries are categorized under System, Status, or Trigger functions and are listed at the
end of each group. The dc source responds to the following commands:
