Scale
Defines the vertical scale in Volts per division. Increasing the scale compresses the
display of the signal.
Remote command:
CHANnel<m>:SCALe on page 1200
Offset
The offset voltage is subtracted to correct a signal with DC offset. The vertical center of
the selected channel is shifted by the offset value and the signal is repositioned within
the diagram area. Negative offset values move up the waveform, positive values move
it down.
The offset of a signal is determined and set by the autoset procedure. The current
value is shown in the waveform label, and it is marked by a small triangle in the grid.
If a Rohde & Schwarz differential probe is connected, the offset is the differential offset.
If a Rohde & Schwarz modular probe is connected, the offset of the selected probe
mode is used. For example, in CM mode, the offset is the common mode offset.
By default, the horizontal grid axis remains in the center when the offset is changed. To
shift the axis together with the waveform, disable Keep Y-grid fixed in ""Settings" >
Appearance > Grid".
Remote command:
CHANnel<m>:OFFSet on page 1201
Position
Moves the selected signal up or down in the diagram. The visual effect is the same as
for Offset but the waveform is adjusted later in the signal flow. While the offset sets a
voltage, position is a graphical setting given in divisions.
By default, the horizontal grid axis remains in the center when the offset is changed. To
shift the axis together with the waveform, disable Keep Y-grid fixed in ""Settings" >
Appearance > Grid".
Remote command:
CHANnel<m>:POSition on page 1201
Coupling
Selects the connection of the channel signal. The coupling determines what part of the
signal is used for waveform analysis and triggering.
"DC 50
Ω"
Connection with 50 Ω termination, passes both DC and AC compo-
nents of the signal.
"DC 1 MΩ"
Connection with 1 MΩ termination, passes both DC and AC compo-
nents of the signal.
