Digital Channels 6
Agilent InfiniiVision 3000 X-Series Oscilloscopes User's Guide 107
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.
