Quick Tips
To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset
to0V.
If you use Autoset w hen no channels are displayed, the instrument turns on channel 1 and scales it.
If you use Autoset and the oscilloscope detects a video signal, the 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. E ach channel
has a dedicated input amplifier and digitizer. Each channel produces a stream of digital data from which the instrument
extracts waveform records.
Sampl
ing Process
Acquisition is the process of sampling an
analog signal, converting it into digital
data
, and assembling it into a w aveform
record, which is then stored in acquisition
memory.
