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.
To display digital channels using AutoScale
When signals are connected to the digital channels — be sure to connect 
the ground leads — AutoScale quickly configures and displays the digital 
channels.
• To configure the instrument quickly, press the [AutoScale] key.
