4. To move the waveform back to the center of the screen, eliminate the offset in the
vertical settings: Press the upper rotary knob in the [Vertical] area (Offset/Position
knob).
The waveform is now displayed in the center of the display, with the x-axis crossing
at 0 V. The waveform might be unstable if the trigger level is above the waveform.
Note: If this step does not work as described, check the function assignment of the
rotary knob. The second row of the signal label shows the vertical position on the
left and the offset on the right. The white value is assigned to the rotary knob, while
the gray value is not. To change the assignment, use "File" menu > "Hardkey
Setup".
5. Tap the "Find level" icon on the toolbar.
The instrument adjusts the trigger level, and a stable waveform is displayed.
6. To examine one pulse in more detail, change the horizontal scale. Try these meth-
ods:
● Touch the screen with two fingers and spread the fingers horizontally.
● Turn the horizontal [Scale] knob.
When you turn the knob, the current scale factor per division is displayed in the
lower right corner of the display. You can switch between a small and large step
size of the scaling factor by tapping the step icon, or by pressing the horizontal
[Scale] knob.
