Example Enabling Continuous Scans | HP FET MULTIPLEXER E1351A/53A

Example Enabling Continuous Scans

INIT:CONT ON	Enables continuous scanning.
SCAN (@100:115)	Sets channel list.
INIT	Starts scanning cycle.

:CONTinuous? INITiate:CONTinuous? queries the scanning state. With continuous scanning enabled, the command returns 1 (ON). With continuous scanning disabled, the command returns 0 (OFF).

Example Query Continuous Scanning State

INIT:CONT ON	Enables continuous scanning.
INIT:CONT?	Query continuous scanning state.

[:IMMediate] INITiate[:IMMediate] starts the scanning cycle and closes the first channel in the channel list. Successive triggers from the source specified by the TRIGger:SOURce command advances the scan through the channel list.

Comments ∙ Starting the Scanning Cycle: The INITiate[:IMMediate] command starts scanning by closing the first channel in the channel list. Each trigger received advances the scan to the next channel in the channel list. An invalid channel list generates an error (see the [ROUTe:]SCAN command).

∙Stopping Scanning Cycles: See the ABORt command.

Example Enabling a Single Scan

SCAN (@100:115)	Sets channel list.
INIT	Starts scanning cycle.
