[Offset/Position (upper knob)]
The upper vertical knob adjusts the following, depending on the selected waveform:
●
Offset or position of an analog channel (adjustable: main menu > "Vertical"). The
visual effect is the same. While the offset sets a voltage, position is a graphical set-
ting given in divisions.
●
Vertical position of a math or reference waveform, serial bus, or logic pod
The knob lights up in the color of the selected waveform. Turn clockwise to move up
the waveform. Pressing the key has the following effects:
●
Analog channels, math waveforms, and buses: sets the value to zero.
●
Reference waveforms: sets to original position or to 0 divisions.
●
FFT and single bits of a pod: set to default value.
●
Pods: set to the center of the display.

[Scale]
Sets the vertical scale in Volts per division to change the displayed amplitude of the
selected waveform. For analog waveforms, the scale value is shown in the waveform
label at the bottom. The knob lights up in the color of the selected waveform.
Turn [Scale] clockwise to stretch the waveform. Doing so, the scale value V/div decrea-
ses. Press the knob to toggle between fine and coarse adjustment.
To get the maximum resolution of the waveform amplitude, make sure that the wave-
forms cover most of the screen's height.

[Logic]
Enables the logic channels. The second keypress opens the menu, where you can
select and configure digital channels for analysis. If the menu is open, pressing the key
disables the logic channels.
Key function requires MSO option R&S RTM-B1.
Logic analyzer functions are described in Chapter 15, "Logic analyzer (option
R&S RTM-B1, MSO)", on page 392.
[Ref]
Displays the reference waveforms with their last configuration. The second keypress
opens the menu, where you can select, create, save and load reference waveforms. If
the menu is open, pressing the key disables the reference waveforms.
Reference waveforms are described in Chapter 7.3, "Reference waveforms",
on page 116.
