4.2.1 HORIZONTAL controls
[Position]
Changes the trigger position, the time distance from the trigger point to the reference
point (trigger offset). The trigger point is the zero point of the diagram. Thus, you can
set the trigger point even outside the diagram and analyze the signal some time before
or after the trigger.
Turn clockwise to move the position to the right, and press the knob to reset the value
to zero. The current value is shown in the information bar.
In zoom and FFT, the knob sets the position in the active diagram. Tap the diagram
that you want to adjust. If a zoom is active, either the position of the zoom window or
the trigger position is changed. In an FFT diagram, the knob changes the center fre-
quency in frequency domain, or the trigger position in time domain.

[Scale]
Adjusts the time scale of the horizontal axis for all signals, also known as timebase.
Turn clockwise to stretch the waveforms - the scale value time/div decreases. Press
the knob to toggle between coarse and fine scale adjustment. The current value is
shown in the information bar.
In a zoom diagram, the knob changes the zoom scale. In an FFT diagram, the knob
changes the span. Tap the diagram that you want to adjust.
