Using Device Clear
Device Clear is an IEEE-488 low-level bus message that you can use to return
the instrument to a responsive state. Different programming languages and
IEEE-488 interface cards provide access to this capability through their own
unique commands. The status registers, the error queue, and all configuration
states are left unchanged when a Device Clear message is received.
Device Clear performs the following actions:
If a measurement is in progress, it is aborted.
The instrument returns to the trigger "idle" state.
The instrument's input and output buffers are cleared.
The instrument is prepared to accept a new command string.
An overlapped command, if any, will be terminated with no "Operation
Complete" indication (applies to the INIT command).
The ABORt command is the recommended method to terminate a
measurement.
