Programmation à distance
99

ON|1 activates the automatic trigger mode.

OFF|0 activates the trigger mode.
To the question TRIG:ATRIG?, the instrument returns the activation status of the automatic
trigger mode.
TRIGger[:SEQuence
{[1]|2|3|4}]:RUN:STATe
(Command/Query)
The TRIG:RUN:STAT <1|0|ON|OFF> command starts or stops the acquisition.

ON|1 acquisition starts.

OFF|0 acquisition is stopped.
To the question TRIG:RUN:STAT?, the instrument returns the trigger status.
TRIGger[:SEQuence
{[1]|2|3|4}]:COUPling
(Command/Query)
The TRIG:COUP <AC|DC> command determines the coupling associated to the main trigger
source.
To the question TRIG:COUP?, the instrument returns the coupling associated to the main
trigger source.
TRIGger[:SEQuence
{[1]|2|3|4}]:DEFine?
(Command/Query)
Returns the description of the indicated sequence :
SEQuence1: EDGE
SEQuence2: PULse
SEQuence3: DELay
SEQuence4: EVENt
TRIGger[:SEQuence
{[1]|2|3|4}]:HYSTeresis
[:STATe]
(Command/Query)
The TRIG:HYST <hysteresis> command sets the amplitude of the hysteresis which rejects
the noise associated to the trigger main source.
<hysteresis> is a value at NR1 format taking following values :

0: no noise reject, hysteresis is about 0.5 div.

3: activated noise reject, hysteresis is about 3 div.
To the question TRIG:HYST?, the instrument returns the amplitude of the hysteresis which
rejects the noise associated to the trigger main source.
TRIGger[:SEQuence
{[1]|2|3|4}]:SLOPe
(Command/Query)
TRIG:SEQ{[1]|2|3|4}:SLOP <POSitive|NEGative> determines :
in SEQuence2 : determines the polarity of the pulse
 POSitive: positive pulse
 NEGative: negative pulse
To the question TRIG:SEQ{[1]|2|3|4<}:SLOP?, the instrument returns the polarity trigger front
or pulse according to the selected SEQuence.
In the other sequences: used to measure the triggering edge of the main source:
 POSitive: rising front
 NEGative: falling front
TRIGger[:SEQuence
{[1]|2|3|4}]:SOURce
(Command/Query)
The TRIG:SOUR <INTernal{1|2|3|4|> command determines the main trigger source of the
instrument.
INTernal{1|2|3|4} corresponds to the trigger source (1, 2, 3, 4 channels) of the instrument on
SCOPIX and SCOPIX BUS.
To the question TRIG:SOUR?, the instrument returns the main trigger source used in.
TRIGger[:SEQuence[4]]
:ECOunt
(Command/Query)
The TRIG:ECO <count|MAX|MIN|UP|DOWN> command sets the number of events used in
the trigger mode delayed by count.
<count> is a value in format NR1 from 3 to 16384.
To the question TRIG:ECO?, the instrument returns the number of events to be counted
before the trigger.
