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.
