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 (for example, during a lengthy
query).
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 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.
