When you change a channel’s volts/division setting, the waveform display can
be set to expand about ground or set to expand about the center of the display.
Expand About 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. If the ground level is off screen, the waveform will expand
about the top or bottom edge of the screen based on where the ground is off
screen.
Expand About Center the displayed waveform will expand about the center
graticule on the display.
Default Library softkey (mixed-signal oscilloscopes only)
Press the Default Library softkey to set the labels in the front-panel Label Library
softkey back to the factory default labels. This will delete all user-defined labels.
Full information about digital channel labels is discussed at the end of the
“Megazoom Concepts and Oscilloscope Operation” chapter.
