Common Commands
Common commands are defined by the IEEE 488.2 standard. They
control generic device functions which could be common among many
different types of instruments. Common commands can be received
and p rocessed by the instrument whether they are sent over the GPIB
as separate program messages or within other program messages.
*CLS
The *CLS (clear status) command clears all the event status registers
summarized in the status byte register.
Syntax *CLS
Description With the exception of the output queue, all queues that are summa-
rized in the status byte register are emptied. The error queue is also
emptied. Neither the event status enable register, nor the service
request enable register are affected by this command.
After the *CLS command, the instrument is left in the idle state. The
command does not alter the instrument setting. *OPC and *OPC?
actions are cancelled.
This command cannot be issued as a query.
*ESE
The *ESE (event status enable) command sets the bits in the event sta-
tus enable register and enables the corresp onding bits in the event sta-
tus register.
Syntax *ESE <integer>
