You can select if the knob changes the position or the reference point in "File" menu >
"Frontpanel Setup" > "Knobs". To set the value to zero, press the knob. The current
value is shown in the input box in the lower right corner of the screen.
"Horizontal position" defines the time distance of the reference point from the zero
point of the diagram. Turn clockwise to move the waveform to the right.
"Reference point" defines the position of the reference point on the screen. Turn clock-
wise to move it to the right. The reference point marks the rescaling center of the time
scale. It is indicated by a gray triangle outline at the top of the diagram. If you modify
the time scale, the reference point remains fixed on the screen, and the scale is
stretched or compressed to both sides of the reference point.
[Scale]
The rotary knob adjusts the time scale for all signals. The time scale is also known as
timebase.
Turn clockwise to stretch the waveforms. Doing so, the scale value time/div decreases.
Press the knob to toggle between coarse and fine scale adjustment.
3.3.4 Vertical Controls
The keys and knobs in the Vertical functional block select a signal and adjust the verti-
cal scale and position of the selected signal.

●
If the channel is on, but not selected: Pressing the key selects the channel wave-
form.
●
If the waveform is selected: Pressing the key opens the "Vertical" dialog box for the
appropriate channel.
