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.
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.
• Center — The displayed waveform will expand about the center of the display.
To disable/enable transparent backgrounds
There is a preference setting for whether measurements, statistics, reference
waveform information, and other text displays have transparent or solid
backgrounds.
1 Press [Utility] > Options > Preferences .
2 Press Transparent to toggle between transparent and solid text display
backgrounds.
