midlevel of the last channel (highest numbered) include in the group.) Use
Timing Diagram mode to measure timing relationships between the waveforms
included in the group.
OFF removes the display of all waveforms in the group. Only the waveforms are
turned off, the group ground reference, trigger position, and trigger bar indicators
remain on screen. You can select, position, and scale a group regardless of
whether it is on or off. Use Off to make room for other groups on screen without
deleting the group.

Figure 3-8: Display Modes
In Figure 3-8, the logic scope is displaying the same group (Group 1) of two
waveforms in the different display modes. (Group 1 was saved to Ref 1 and
Ref 2 and both reference groups were displayed in the modes indicated.) Note
that while the Analog group shows the difference in amplitude between the
overlapped waveforms, BusForm and Timing Diagram show the waveforms as if
they had the same amplitudes. This difference occurs because the logic scope
displays BusForm and Timing Diagram waveforms as HIGH or LOW logic
levels based on their relationship to thresholds.
