The readout shows the time difference 't' between the cursors and the voltage difference between the two markers (See Figure 1-20). The signal frequency is displayed behind 1/t if exactly 1 signal period is between the cursors. Making Rise Time Measurements To measure rise time, do the following: From Scope mode, display the Cursor Key functions. Press to highlight (rise time). Observe that two horizontal cursors are displayed. If only one trace is displayed, select MANUAL or AUTO. AUTO automatically does steps 4 to 6. For multiple traces select the required trace A or B. Move the upper cursor to 100% of the trace height. A marker is shown at 90%. 1 Using The Test Tool Making Cursor Measurements Highlight the other cursor. } Move the lower cursor to 0% of the trace height. A marker is shown at 10%. Figure 1-21.

The readout shows the time difference ‘t’ between the
cursors and the voltage difference between the two
markers (See Figure 1-20).
The signal frequency is displayed behind 1/t if exactly 1
signal period is between the cursors.
Making Rise Time Measurements
To measure rise time, do the following:
±
From Scope mode, display the
Cursor Key functions.
²
Press to highlight
(rise time).
Observe that two horizontal
cursors are displayed.
³
If only one trace is displayed,
select MANUAL or AUTO. AUTO
automatically does steps 4 to 6.
For multiple traces
select the
required trace A or B.
´
Move the upper cursor to 100%
of the trace height. A marker is
shown at 90%.
µ
Highlight the other cursor.
⑥
Move the lower cursor to 0% of
the trace height. A marker is
shown at 10%.
