D Readout. The D readouts indicate the difference between the cursor
positions.
@ Readout. For H Bar or V Bar cursors, the voltage readout after the
@ symbol indicates the location of the active cursor relative to
zero volts. For V Bar cursors, the time readout after the @ symbol
indicates the location of the active cursor relative to the trigger point.
Cursor Interaction with Preview. If you change a vertical or horizontal
control setting while acquisition is stopped or it is waiting for trigger,
the cursors move with the waveforms and cursor measurements
remain valid.
Taking Gray-Scale Measurements. Using cursors is often the best way to
take simple measurements on waveforms that contain significant
gray-scale information. The automatic measurements operate only
on the latest acquisition, not on the previous acquisitions that are
displayed in gray scale. However, you can set the cursors to surround
and measure the gray-scale area of the waveform.
