Adjusting the analog channel’s vertical scale and offset
You can use the vertical scale and offset knobs, the vertical user interface controls,
or the Channel dialog box to adjust the vertical scale and offset.
• The vertical scale knob is the larger of the two knobs for a channel. Turn it to
make the waveform bigger (fewer volts per division) or smaller (more volts per
division).
• You can also mouse over or touch the vertical scale field and use the resulting
controls to set an exact value for the scaling.
• The vertical offset knob is the smaller of the two knobs for a channel. Turn it to
move the waveform up or down.
• You can click and drag the waveform or its ground reference indicator to the
desired vertical offset if the grid is in drag mode .
• Click Setup > Channel N... or click a channel number to open the Channel dialog
box, in which you can set the vertical scale, offset, skew, and labels. You can
also specify the characteristics of a probe, or perform a probe calibration.
For Keysight Technologies probes that are compatible with AutoProbe I
interfaces, the oscilloscope will automatically set these characteristics (except
for skew) after identifying the probe when it is connected to the channel input.
NOTE
Using an Analog Channel as Trigger
Any analog channel can be used as a trigger source. If you need a trigger but do not need all
analog channels, you can use an analog channel as a trigger without displaying it by turning
the analog channel display off.
