INITiate, CONTinuous | HP FET MULTIPLEXER E1351A/53A manual

INITiate

	The INITiate subsystem selects continuous scanning cycles and starts the
	scanning cycle.
Subsystem Syntax	INITiate
	:CONTinuous <mode>
	:CONTinuous?
	[:IMMediate]
:CONTinuous	INITiate:CONTinuous <mode> enables or disables continuous scanning
	cycles for the switchbox or scanning voltmeter.

mode	Boolean	0 1 ON OFF

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 specified 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. Continuous scanning can be stopped by the ABORt command for non-downloaded scans, and by a system reset or a power off for downloaded scan lists.

∙Scanning a Set Number of Cycles: The INITiate:CONTinuous OFF or INITiate:CONTinuous 0 command goes through the scan list the number of times specified by the ARM:COUNt 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 opens the last channel in the channel list, and if the number of cycles has not reached the ARM:COUNt parameter, returns to the beginning of the scan list and closes the first channel. When the number of cycles equals the ARM:COUNt parameter, the scanning cycle stops. Note that ARM:COUNt does not apply to downloaded scan lists.

∙Stopping Continuous Scans: Continuous scanning can be stopped by the ABORt command for non-downloaded scans, and by a system reset or a power off for downloaded scan lists.

∙Related Commands: ABORt, ARM:COUNt, *RST, TRIGger, TRIGger:SOURce

∙*RST Condition: INITiate:CONTinuous OFF
