Chapter3 IEEE-488 Command Reference
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 this chapter.
Common Commands
Common commands begin with an * and consist of three letters (command)
IEEE 488.2 standard to perform some common interface functions. The
electronic loads respond to the required common commands that control status
reporting, synchronization, and internal operations. The electronic loads also
respond to optional common commands that control triggers, power-on
conditions, and stored operating parameters.
Common commands and queries are listed alphabetically. If a command has a
corresponding query that simply returns the data or status specified by the
command, then both command and query are included under the explanation
for the command. If a query does not have a corresponding command or is
functionally different from the command, then the query is listed separately. The
description for each common command or query specifies any status registers
affected. Refer to chapter “Programming the Status Registers”, which explains
how to read specific register bits and use the information that they return.
