13-4
Status Structure
Clearing registers and queues
When Model 6514 is turned on, the bits of all registers in the status structure are clear (reset
to 0) and the two queues are empty. Commands to reset the event and event enable registers, and
the error queue are listed in Table 13-1. In addition to these commands, any enable register can
be reset by sending the 0 parameter value with the individual command to program the register.
NOTE
SYSTem:PRESet and *RST have no effect on status structure registers and queues.
Table 13-1
Common and SCPI commands — reset registers and clear queues
Commands
Description
Ref
To reset registers:
*CLS
Reset all bits of the following event registers to 0:
Note 1
Standard event register
Operation event register
Measurement event register
Questionable event register
STATus
STATus subsystem:
:PRESet
Reset all bits of the following enable registers to 0:
Operation event enable register
Measurement event enable register
Questionable event enable register
Note 1
To clear error queue:
*CLS
Clear all messages from error queue
Note 2
STATus
STATus subsystem:
:QUEue
Error queue:
:CLEar
Clear messages from error queue
Note 3
SYSTem
SYSTem subsystem:
:ERRor
Error queue:
:CLEar
Clear messages from error queue
Note 3
Notes:
1. The standard event enable register is not reset by STATus:PRESet or *CLS. Send the 0 parameter value
with *ESE to reset all bits of that enable register to 0 (see “Status Byte and Service Request commands”).
2. STATus:PRESet has no effect on the error queue.
3. Use either of the two clear commands to clear the error queue.
