Memory Bar
When the real-time mode is selected, the memory bar is displayed above the
graticule area. Figure 4-2 shows the components of the memory bar.
The memory bar display line represents the entire waveform record. The
memory bar represents the displayed portion of the waveform record. The
memory bar at the top of the display moves as the delay changes. The "T"
indicates the location of the trigger point within the waveform record.
You can view the waveform from three different positions with respect to the
trigger point by selecting left, center, or right with the reference softkey.
When the acquisition is stopped, you can place the display at any portion of
the waveform record by changing the delay setting. The delay knob moves
the acquisition display relative to the trigger point.
