Underthrow
This trigger type monitors a pulse that exceeds one threshold and then drops below
the threshold without exceeding the second threshold. This type of trigger is
typically used to find pulses that do not reach a valid logic level.

Buffer
The buffer is used to store the captured waveform data for real-time and playback
display.
The oscilloscope can capture and store waveforms. Select a waveform from the
waveform buffer by tapping the Previous or Next button.
The waveform buffer displays the current waveform number and the total number of
stored waveforms.
