10 U2761A Programmer’s Reference

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.
