TRIGger[:SEQuence
{[
1]|2|3|4}]
:FILTer:HPASs[:STATe]
(Command/Query)
The TRIG:FILT:HPAS <1|0|ON|OFF> command validates or devalidates the reject of the low
frequencies associated to the main trigger source.

1|ON: activates the reject of the low frequencies (LF Reject coupling)

0|OFF: deactivates the reject of the low frequencies; the DC coupling is then
activated.
To the question TRIG:FILT:HPAS?, the instrument returns the activation status of the low
frequencies reject associated to the trigger source.
TRIGger[:SEQuence
{[1]|2|3|4}]
:FILTer:LPASs[:STATe]
(Command/Query)
To the question TRIG:FILT:LPAS?, the instrument returns the activation status the reject of
the high frequencies associated to the trigger source.

1|ON: activates the high frequencies reject (HF Reject coupling)

0|OFF: deactivates the high frequencies reject; the DC coupling is then activated.
To the question TRIG:FILT:LPAS?, the instrument returns the activation status the reject of
the high frequencies associated to the trigger source.
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]|3|4]
: HOLDoff
(Command/Query)
The TRIG:HOLD <time|MAX|MIN|UP|DOWN> command sets the inhibition time of the trigger
(Holdoff).
<time> is a value in format <NRf>, it may be followed or not by a multiple and by the unit.
By default the value is expressed in second.
To the question TRIG:HOLD?, the instrument returns the trigger Holdoff time.
Response format: <measured value><NL>
value in format <NR3> expressed in second.
TRIGger[:SEQuence
{[1]|2|3|4|}]:LEVel
(Command/Query)
Used in the Seq. 1 to 4, the TRIG:LEV <level|MAX|MIN|UP|DOWN> command sets the trigger
level of the main source.
<level> is a value in format NRf, it may be followed or not by a multiple and by the unit.
By default, the value is expressed in volt.
To the question TRIG:LEV?, the instrument returns the trigger level of the main source in
SEQuence1.
Response format: <measured value><NL>
value in format <NR3> expressed in volt.
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.
