Each channel key turns on an analog channel, selects it, and opens the "Channel" menu
with the vertical settings of the selected channel. The key is illuminated in the channel
color, if the channel is active.
The effect of the keypress depends on state of the channel:
●
If channel is off: Pressing the key turns the channel on and selects it. The rotary knobs
alongside light up in the channel color.
●
If the channel is on: Pressing the key selects the channel waveform and open its
channel setup menu.

SIGNAL OFF
Turns the selected signal off and selects the next channel, math or reference waveform.
The key lights up in the color of the selected signal and changes the light according to
the new selection.

POSITION / OFFSET
The rotary knob adjusts the vertical position or the DC offset (if enabled). It lights up in
the color of the selected waveform. Pressing the key toggles the parameter, the current
parameter and its value are shown in a temporary label marked with the channel color.
Note: By default, offset is disabled. Press "Offset" in the "Channel" menu to enable the
offset.
POSITION ← POSITION / OFFSET
Position changes the vertical location of the selected channel, math, or reference wave-
form, or of the decoded bus signal. Turn clockwise to move the waveform up. At zero-
crossing, the knob shortly snaps in and the setting is kept constant to simplify the zero-
setting.

OFFSET ← POSITION / OFFSET
The offset voltage is subtracted to correct an offset-affected signal. The vertical center
of the selected channel is shifted by the offset value and the signal is re-positioned within
the diagram area.
