7.3 Pulse Width Trigger
Pulse width trigger can set the oscilloscope at specific width and generated the positive pulse or negative
pulse when meet the trigger condition. Pulse width trigger menu can set source, condition, the upper
/lower limit of pulse width, polarity of pulse width (positive and negative), trigger coupling, trigger mode,
etc. As shown in Figure 7-2.

Condition
Select trigger condition:">","<","≤≥".
a.
>：It will be generated when the pulse width of the trigger signal is greater than the pulse width
setting, it can set the lower limit of pulse width.
b.
<：It will be generated when the pulse width of the trigger signal is smaller than the pulse width
setting, it can set the upper limit of pulse width.
c.
≤≥：It will be generated when the pulse width of the trigger signal is basically similar to the pulse
width setting or the pulse width of the trigger signal is in the setting scope, it can set the
lower/upper limit of pulse width.
(2) The upper /lower limit of pulse width
Compare the setting pulse width value with the signal pulse width. The trigger will be generated when
the condition is met. The range can be set to 1 ns ~4 s.
