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 the chapter. The dc source responds to the following common commands:

Table 8-2. Common Commands Syntax
*CLS Clear status
*ESE <n> Standard event status enable
*ESE? Return standard event status enable
*ESR? Return event status register
*IDN? Return instrument identification
*OPC Enable "operation complete" bit in ESR
*OPC? Return a "1" when operation complete
*OPT? Return option number
*PSC <bool> Power-on status clear state set/reset
*PSC? Return power-on status clear state
*RCL <n> Recall instrument state
*RST Reset
*SAV <n> Save instrument state
*SRE <n> Set service request enable register
*SRE? Return service request enable register
*STB? Return status byte
*TRG Tr igger
*TST? Perform selftest, then return result
*WAI Hold off bus until all device commands done
