Using Device Clear to Halt Measurements
Device clear is an IEEE-488 low-level bus message which can be used to
halt measurements in progress. 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.
• All measurements in progress are aborted.
• The power meter returns to the trigger “idle state”.
• The power meter’s input and output buffers are cleared.
• The power meter is prepared to accept a new command string.
