it closed in the closed position.

Affect on Scan Complete Status Bit: Aborting a scan will not set the "scan
complete" status bit.
•
Stopping Scans Enabled from HP-IB Interface: When a scan is enabled
from the HP-IB interface, and the trigger source is not
clear the interface to stop the scan. In the BASIC programming language, this
is done by executing the CLEAR command for your interface (CLEAR 7, for
example).When the scan is enabled from the HP-IB interface and the trigger
source is TRIGger:SOURceBUS
command over the HP-IB bus.
Clearing the HP-IB interface during a scan leaves the last channel the scan closed in
the closed position and does not set the "scan complete" status bit.
•
Stopping Scans by using the terminal: You may use a terminal connected to
the HP E1405/1406 command module to stop any scan.
If the scan was started from the terminal, and the trigger source is
, send the
BUS ABORt
the terminal and some other trigger source is being used, a Ctrl-c will send an
interface CLEAR to the instrument and abort the scan. Sending Ctrl-r also
sends an interface CLEAR to the instrument and additionally performs a reset
( *RST ) on the instrument. (See your HP E1405/E1406 Command Reference
for details on the terminal interface.)
If the scan was started from the HP-IB interface, but you wish to stop it by
using the terminal, first make sure that the correct instrument (e.g.,SWITCH at
desired logical address) is selected by using the terminal soft keys. Then send a
Ctrl-r. This will send an interface CLEAR to the HP-IB task, but will not
place the instrument in the reset state with respect to the HP-IB task. These
actions will occur regardless of the trigger source setting.
