You do not need to "eject" the USB mass storage device before removing it. Simply
ensure that any file operation you've initiated is done, and remove the USB drive
from the oscilloscope's host port.
Do not connect USB devices that identify themselves as hardware type "CD"
because these devices are not compatible with the InfiniiVision X-Series
oscilloscopes.
If two USB mass storage devices are connected to the oscilloscope, the first one is
designated "\usb" and the second one is designated "\usb2".

To choose "expand about" center or ground
When you change a channel's volts/division setting, the waveform display can be
set to expand (or compress) about the signal ground level or the center of the
display.
To set the waveform expansion reference point:
1 Press [Utility] > Options > Preferences > Expand and select:
• Ground — The displayed waveform will expand about the position of the
channel's ground. This is the default setting.
The ground level of the signal is identified by the position of the ground level
(
) icon at the far-left side of the display.
The ground level will not move when you adjust the vertical sensitivity
(volts/division) control.
