40 Keysight Infiniium 90000A Series Oscilloscopes User’s Guide
2 Using the Oscilloscope
Adjusting the Vertical Settings
Use the vertical controls to set the vertical scaling (volts per division) and vertical
offset for each analog channel. You can also turn the display on or off for a
particular channel.
Turning an analog channel on or off
• To turn an analog channel on or off, press the channel number key on the front
panel or click the Add Waveforms button . When you turn off a channel, the
current vertical scale and offset fields for that channel disappear.
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.
