Remote command:
SENSe7:TRIGger:SOURce
on page 767
Trigger Level
Entering the trigger level
Recording is triggered according to the ""Trigger Slope"" when this level is overranged
or underranged.
When measurement has been started or recording has been triggered (in the case of
continuous measurement), a new recording cycle is not armed again until the trigger
threshold is violated in the opposite direction.
Remote command:
SENSe7:TRIGger:LEVel
on page 767
Trigger Slope
Used to select the signal edge on which measurement is to be triggered (trigger slope).
"Rising" "Triggering" takes place when the level on the measurement channel
selected as trigger source exceeds the trigger threshold for the first
time.
(Re-)arming takes place as soon as a level below the trigger thresh-
old occurs.
"Falling" "Triggering" takes place when the level on the measurement channel
selected as "Trigger Source" drops below the trigger threshold for the
first time.
(Re-)"arming" takes place as soon as a level above the trigger thresh-
old occurs.
Remote command:
SENSe7:TRIGger:SLOPe
on page 767
Pretrigger
Used to activate the pretrigger and to enter the pretrigger interval in seconds:
The pretrigger is deactivated by entering a pretrigger time of 0.0 s.
Entering a pretrigger time shifts the trigger point within the recording time selected as
"Trace Length".
The pretrigger memory is 19200 samples in size, i.e. 4 % of the maximum possible
trace length. With a compressed waveform display ("Compressed" or "Undersample"),
the maximum possible pretrigger time (and the trace length) is increased by the com-
pression factor.
