Halting an Output in Progress
You can send a device clear at a ny 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 follow ing actions .
• The power supply’s input and output buffers are cleared.
• The power supply is prepared to accept a new comm and 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 L ibrary 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 op era tion, sen ding the <C trl -C> cha rac ter will pe rform 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 54
in chap ter 3 for furthe r detai ls .
