4. pulse width trigger

The pulse trigger lets the oscilloscope trigger according to the pulse width of the signal. Unusual signals

can be detected by adjusting the pulse width conditions.

In pulse trigger mode, the setting information is displayed at the bottom right of the screen, e.g.:

indicates that pulse trigger on CH1 with DC coupling has been selected and the polarity

is positive and the trigger level is 0.00mV.
