Scrolling Through The Waveform Display; Reference Points; Trigger; User Defined (X, O) - HP 64700 series User Manual

Scrolling through the
When the time per division is decreased, not all of the trace can be
displayed on the screen. However, you can scroll the trace across the
Waveform Display
screen by pressing the CTRL left arrow and CTRL right arrow keys.
The portion of the trace that is currently displayed is represented by a
bar at the bottom of the screen.

Reference Points

Three reference points appear in the waveform display. The first is the
trigger point. The two remaining reference points are movable, and
you can place them at areas of interest in the trace.

Trigger

The trigger point is represented by the vertical dashed line. The trigger
point is the actual trigger condition (pattern, edge, or glitch) plus the
trigger delay.

User Defined (X, O)

The user defined reference points can be moved anywhere in the
display. These points are also represented by vertical dashed lines, and
they are labeled "x" and "o". The top of the waveform display shows
time between these two points and the time between them and the
trigger.
Cursor moves (X, O, X & O) The third field from the top allows
you to select which reference points the cursor will move, "x", "o", or
both "x & o".
Magnify About (X or O) Toggling the "display about" value from
"x" to "o" causes the waveforms to be displayed about the different
reference points.
