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 list and the scan cycle repeats.
• Non-Continuous Scanning Operation: Non-continuous scanning is
enabled with the
INITiate:CONTinuous OFF or INITiate:CONTinuous
0
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. At the end of the scanning cycle, the last
channel in the channel list is closed.
• Stopping Continuous Scans: See the ABORt command.
• Related Commands: ABORt, ARM:COUNt, TRIGger,
TRIGger:SOURce
Example Enabling Continuous Scans
This example enables continuous scanning of channels 00 through 02 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 Enables continuous scanning.
SCAN (@100:102) Defines channel list.
INIT Start scan cycle, close channel 00.
