5. Common Commands
Common commands begin with an * and consist of three letters (command) or three letters and a
? (query). Common commands are defined by the IEEE 488.2 standard to perform some common
interface functions. The 3000Lx and the 4500Lx respond to the required common commands that
control status reporting, synchronization, and internal operations. The 3000Lx and the 4500Lx
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 7 under Programming the Status and Event Registers which explains
how to read specific register bits and use the information that they return.
