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. 
• 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.
