6.5.4 Pulse width trigger
Pulse trigger occurs according to the width of pulse. The abnormal signals can be detected
through setting up the pulse width condition.
In Pulse Width Trigger mode, the trigger setting information is displayed on bottom right of the
screen, for example
,
indicates that trigger type is pulse width, trigger source
is CH1, coupling is DC, polarity is positive, and trigger level is 0.00mV.

The slope mode allows the oscilloscope to trigger on the rising / falling edge of a signal within a
specified period of time. In the slope trigger mode, the setting information is shown on the lower
right edge of the screen, e.g:
indicates that the slope trigger has been selected
on CH1, slope increasing and the difference between the up-level and low-level threshold value is
0.00mV.
