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.

internal OSC.

INTernal[1]

 

internal PLL

INTernal2

 

CLK-IN

EXTernal2

 

 

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
