Programming the Instrument Trigger Modes

External Width

Set External Width mode using the :EWIDth[:STATe] command:

:ARM:EWIDth ON Switch on EXT WIDTH mode

This command disables the arm-trigger system. The arm-trigger system is

reenabled by switching OFF EWIDth mode.

Pulses

Set Pulses mode by setting the :TRIGger:COUNt to 1 so that a single

triggered pulse period is generated for every arm event. The trigger

source sets the pulse period:

:TRIGger:COUNt 1 Single pulse period per arm event

:TRIGger:SOURce INTernal1 Pulse period from internal osc.

:DIGital:PATTern OFF Disable pattern data.

NOTE The internal PLL (INTernal2) cannot be used as :TRIGger:SOURce

(pulse period source) if it is already being used as ARM:SOURce

(triggering rate).

Note that in triggered pulses mode the pulse period source is not relevant

because a single pulse is generated for each ARM event.

Burst

Set Burst mode by setting the :TRIGger:COUNt to the burst length

required. The trigger source sets the pulse period for the pulses within

the burst.

:TRIGger:COUNt 16 Burst of 16 pulse periods

:TRIGger:SOURce INTernal1 Pulse period from internal osc.

:DIGital:PATTern OFF Disable pattern data

Pulse period Source :TRIGger SOURce
