Using the Oscilloscope
If you are not using a particular analog channel, you can turn it off to simplify
the waveform display and increase the display update rate. Functions continue
to run on a channel source that is turned off. Data acquisition continues for a
channel if a function requires it.
Adjusting an analog channel’s vertical scale and offset
To adjust the vertical scale and offset, use the vertical scale and offset knobs,
vertical user interface controls, or Channel dialog box.
The vertical scale knob is the larger of the two knobs for a channel. Turn the knob
to make the waveform bigger (fewer volts per division) or smaller. 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 knob for a channel. Turn it to move the
waveform up or down.
You can drag the waveform or its ground reference indicator to the desired vertical
offset if the grid is in drag mode .
Choose 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 II 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.
