INITiate
The INITiate subsystem selects continuous scanning cycles and starts the
scanning cycle.
Subsystem Syntax INITiate
:CONTinuous ON | OFF | 1 | 0
:CONTinuous?
[:IMMediate]
:CONTinuous INITiate:CONTinuous ON | OFF | 1 | 0 enables or disables continuous
scanning cycles for the switchbox.
Parameters
Parameter Name Parameter Type Range of Values
ON | OFF | 1 | 0 boolean ON | OFF | 1 | 0
Comments • Continuous Scanning Operation: Continuous scanning is enabled
with the
INITiate:CONTinuous ON or INITiate:CONTinuous 1
command. Sending the INITiate[:IMMediate] command closes the
first channel in the channel list.
• Each trigger from a trigger source selected by the TRIGger:SOURce
command advances the scan through the channel list. A trigger at
the end of the channel list closes the first channel in the channel list
and the scan cycle repeats.
• Non-Continuous Scanning Operation: This is enabled with the
INITiate:CONTinuous OFF or INIT:CONT 0 command. Sending the
INIT:IMM command closes the first channel in the channel list.
Each trigger from a trigger source selected by the
TRIGger:SOURce
command advances the scan through the channel list. At the end of
the scanning cycle, all channels in the channel list are closed.
• Stopping Continuous Scans: See the ABORt command.
• Related Commands: ABORt, ARM:COUNt, TRIGger
• *RST Condition: INITiate:CONTinuous OFF
Example Enabling Continuous Scans
This example enables continuous scanning of channels 00 through 03 of a
single-module switchbox. Since
TRIGger:SOURce IMMediate (default) is
set, use an interface clear command (such as
CLEAR) to stop the scan.
INIT:CONT ON ! Enable continuous scanning
SCAN (@100:103) ! Define channel list
INIT ! Start scan cycle, close channel 00
