Halting an Output in Progress
You can send a device clear at any time to stop an output in progress over 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 power supply’s input and output buffers are cleared.
• The power supply 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.
IOCLEAR (705)
Note All remote interface configurations can be entered only from the front panel. See
‘‘Remote Interface Configuration’’ in chapter 3 to configure for GPIB or RS-232
interface before operating the power supply remotely.
For RS-232 operation, sending the <Ctrl-C> character will perform the
same operation as the IEEE-488 device clear message. The power
supply’s DTR (data terminal ready) handshake line is set true following
a device clear message. See ‘‘DTR/DSR Handshake Protocol’’, on page 66
in chapter 3 for further details.
