Common Commands
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 instru-
ments. Common commands can be received and processed 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 summarized 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 status enable reg-
ister and enables the corresponding bits in the event status register.
Syntax *ESE <integer>
*ESE?
<integer> is a mask from 0 to 255.
