Digital Channels 6Acquiring waveforms using the digital channelsWhen you press [Run/Stop] or [Single] to run the oscilloscope, theoscilloscope examines the input voltage at each input probe. When thetrigger conditions are met the oscilloscope triggers and displays theacquisition.For digital channels, each time the oscilloscope takes a sample it comparesthe input voltage to the logic threshold. If the voltage is above thethreshold, the oscilloscope stores a 1 in sample memory; otherwise, itstores a 0.To display digital channels using AutoScaleWhen signals are connected to the digital channels — be sure to connectthe ground leads — AutoScale quickly configures and displays the digitalchannels.• To configure the instrument quickly, press the [AutoScale] key.Figure 8Example: AutoScale of digital channels (MSO models only)Agilent InfiniiVision 2000 X-Series Oscilloscopes User's Guide 83
