(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.
(Command/Query)
TRIG:SEQ{[1]|2}: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}: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
(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.
(Command/Query)
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:
(Command/Query)
The TRIG:TYP <INFerior|SUPerior> command determines the trigger type on pulse width :
EQUate : trigger on pulses of duration equal to that one specified with the TRIG:SEQ2:DEL
„
command.
SUPerior : trigger on pulses of duration superior to that one specified with the TRIG:SEQ2:DEL
„
command.
INFerior : trigger on pulses of duration inferior to that one specified with the TRIG:SEQ2:DEL
„
command.
To the question TRIG:TYP?, the instrument returns the trigger type on pulse width.
Response format:
(Command/Query)
The TRIG:DEL <time|MAX|MIN|UP|DOWN> command sets the duration of pulse comparison.
<time> is a value in format <NRf>, it may be then followed or not by a multiple and by the unit.
By default the value is expressed in second.
To the question TRIG:DEL?, the instrument returns the trigger delay of the main source or the T1 pulse
time according to the selected sequence.
Response format:
value in format <NR3> expressed in second.
<measured value><NL>value in format <NR3> expressed in volt.
<EQU|SUP|INF ><NL>
