Using Device Clear
You can send a device clear at any time abort a SCPI command that may be hanging up the GPIB
interface. 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 input and output buffers of the dc source are cleared.
♦ The dc source is prepared to accept a new command string.
The following statement shows how to send a device clear over the GPIB interface using Agilent BASIC:
CLEAR 705 IEEE-488 Device Clear
The following statement shows how to send a device clear over the GPIB interface using the GPIB
command library for C or QuickBASIC:
