Using Device Clear
Device Clear is an IEEE-488 low-level bus message which you can use
to return the instrument to a responsive state. Different programming
languages and IEEE-488 interface cards provide access to this capa bi li ty
through their own unique commands. The status registers, the error
queue, the alarm queue, and all configuration states are left unchanged
when a Device Clear message is received. Device Clear performs the
following actions.
•If a scan is running, it is aborted.
•The instrument returns to the scan trigger “idle state.”
•The instrument’s input and output buffers are cleared.
•The instrument is prepared to accept a new command string.
For RS-232 operation, sending the <Ctrl-C> character will perform
the equivalent operations of the IEEE-488 Device Clear message.
Note: The ABORt command is the recommended way to terminate a scan.
