Programming Reference

Programming the Instrument Trigger Modes

Use the :ARM subsystem to select the overall triggering mode of the instrument (CONTINUOUS, TRIGGERED, GATED, EXT WIDTH), and the :TRIGger subsystem to select the pulse period source, triggering and number of pulse periods per :ARM event (BURST or PATTERN length).

Continuous

Set Continuous mode by arming the instrument from its internal oscillator:

:ARM:SOURce IMMediate Arm from internal oscillator.

Triggered

Set Triggered mode by arming the instrument on edges from the EXT INPUT:

:ARM:SOURce EXTernal1

Arm from EXT INPUT

:ARM:SENSe EDGE

Arm on edge

:ARM:SLOPe

POSitive

Arm

on positive edge

:ARM:LEVel

1V

Set

EXT INPUT threshold

You can also arm the instrument from the PLL and set the frequency (or period) of the PLL to the required triggering rate:

 

:ARM:SOURce INTernal2

Arm

from PLL

 

:ARM:SENSe

EDGE

Arm

on edge

 

:ARM:SLOPe

POSitive

Arm

on positive edge

 

:ARM:FREQuency <value> Set

PLL frequency

NOTE

The PLL (INTernal2) cannot be used as :ARM:SOURce (triggering rate) if

 

it is already being used as :TRIGger:SOURce (pulse period source).

Gated

Set Gated mode by arming the instrument on levels from the EXT INPUT:

:ARM:SOURce EXTernal1

Arm from EXT INPUT

:ARM:SENSe

LEVel

Arm

on signal level

:ARM:SLOPe

POSitive

Arm

on positive level
