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. Each channel
has a dedicated input amplier and digitizer. Each channel produces a stream of digital data from which the instrument
extracts waveform records.

ng Process
Acquisition is the process of sampling an
analog signal, converting it into digital
data,
and assembling it into a waveform
record, which is then stored in acquisition
memory.

Real-Time Sampling
Record points
MDO3000 Series oscilloscopes use
real-time sampling. In real-time sampling,
the instrument digitizes all of the points it
acquires using a single trigger event.
