Subsystem Syntax INITiate

: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
