*OPC
Command Syntax
*OPC
Parameter: None
Short form: *OPC
Function: When all operations have been completed, event 800 is written to the
error/event queue (if enabled by STAT:QUE:ENAB). At the same time, this
command allows the OPC bit in the standard event register to be set. This
can be used to trigger a serial poll, see *ESR for details. If there are no
pending operations these actions are performed immediately. This
command should be sent each time the OPC bit is allowed to be set.
Default: -
Note:
It is intended that the *OPC command should be the last command in a
program message.
