Acquiring waveforms using the digital channels
When you press Run/Stop or Single to run the oscilloscope, the
oscilloscope examines the input voltage at each input probe.
When the trigger conditions are met the oscilloscope triggers
and displays the acquisition.
For digital channels, each time the oscilloscope takes a sample
it compares the input voltage to the logic threshold. If the
voltage is above the threshold, the oscilloscope stores a 1 in
sample memory; otherwise, it stores a 0.
