Width
The width trigger compares the pulse width (duration) with a given time limit. It detects
pulses with an exact pulse width, pulses shorter or longer than a given time, as well as
pulses inside or outside the allowable time range.
The instrument triggers if the pulse does not cross the specified voltage treshold twice.
The pulse width is measured at the trigger level.
Comparison
Sets how the measured pulse width is compared with the given limit(s).
"ti<t, ti>t"
Triggers on pulse width shorter or longer than the reference "Time t".
"ti=t"
Triggers on pulse width equal to the reference "Time t" if "Variation"
Δ
t
= 0.
If "Variation"
≠
0: this setting triggers on pulses within the range t
±Δ
t.
"ti
≠
t"
Triggers on pulses unequal to the reference "Time t", if "Variation"
Δ
t =
0.
If "Variation"
≠
0: this setting triggers on pulses outside a range t
±Δ
t.
"Inside, Out-
side"
Triggers on pulses inside or outside a range specified with "Time t1"
and "Time t2".
This method is an alternative setting to the range definition with "Time
t" and "Variation". The values are interdependent. "Variation" and "Time
t" are adjusted If you change t1 and t2, and vice versa.
Remote command:
Polarity
Sets the polarity of the pulse.
"Pos."
Positive going pulse, the width is defined from the rising to the falling
slopes.
"Neg."
Negative going pulse, the width is defined from the falling to the rising
slopes.
