2. Toggle Display ‘T’ @ Trigger Point (side) to select whether or not to
display ‘T’ indicating the trigger point. You can select ON or OFF. (The
trigger point indicates the position of the trigger in the waveform record.)
3. Press Trigger Bar Style (side) to select either the short or the long trigger
bar or to turn the trigger bar off. (See Figure 3–18. Note that both styles are
shown for illustrating purposes, but you can only display one style at a time.)
The trigger bar is only displayed if the trigger source is an active, displayed
waveform. Also, two trigger bars are displayed when delay triggerable
acquisitions are displayed — one for the main and one for the delayed
timebase. The trigger bar is a visual indicator of the trigger level.
Sometimes, especially when using the hardcopy feature, you may want to
display the current date and time on screen. (To find more information
displaying and setting date and time, see Date/Time Stamp the Hardcopy on
page 3–123.)
4. Press Display Date/Time (side) to turn it on or off. Push Clear Menu to see
the current date and time.
