1.3 The Main Screen
After startup the screen should look as shown below:
The left side of the display is taken up by the waveform display and a scroll bar to move through
the acquired waveform (the record is longer that what is displayed). On the right side you can
see that the controls are grouped in several functional blocks (we will explain each of them in
more detail later):

Acquisition: Main control of acquisition process

Display: Determines how the acquired data is to be displayed.

Vertical: Controls the input amplification/attenuation for each of the two input channels.

Levels: Sets the voltage offset for each channel, and the trigger threshold level.

Horizontal: Controls the sampling speed, delay, and sampling method.

Trigger: Defines the trigger source.
On the bottom there is a status line that displays the cursor information (right now the cursors
are turned off), which you use to make measurements on the displayed waveforms (e.g. to
determine the signal amplitude or frequency).
On the top of the screen you find the menu containing several items:

File (to save the displayed waveforms in numerical format, and to save and restore the
DPScope II
’s software settings)
