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

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
