Using Device Clear
Device Clear is an IEEE-488 low-level bus message that you can use to
return the function generator 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.
• The function generator’s input and output buffers are cleared.
• The function generator is prepared to accept a new command string.
• For RS-232 operation, sending the <Break> character will perform
the equivalent operations of the IEEE-488 Device Clear message.
• An overlapped command, if any, will be terminated with no
“Operation Complete” indication (applies to the *TRG command).
Any sweep or burst in progress will be aborted immediately.
