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 Keysight BASIC.
– The following statement shows how to send a device clear over the GPIB
interface using the GPIB Command Library for C or QuickBASIC.
CLEAR 705 IEEE-488 Device Clear
IOCLEAR (705)
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 88 for further details.
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.
