Quick Tips
To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset t o 0 V.
If you use Autoset when no channels are displayed, th e instrument turns on channel one (1) and scales it.
If you use Autoset and the oscilloscope detects a video signal, th e oscilloscope automatically sets the trigger type to video and
makes other adjustments to display a stable video signal.
Acquisition Concepts
Before a signal can be displayed, it must pass through the input channel where it is scaled and digitized. Each ch annel has a
dedicated input amplifier and digitizer. Each channe l produces a s tre am of digital data from which the instrument extracts waveform
records.
