Making Rise Time Measurements
To measure rise time, do the following:
1 From scope mode, display the
cursor key labels.
2 Press to highlight (rise time).
Observe that two horizontal
cursors are displayed.
3 For multiple traces select the
required trace A, B, or M (if a
math function is active).
4 Select MANUAL or AUTO (this
automatically does steps 5 to 7).
5 Move the upper cursor to 100% of
the trace height. A marker is
shown at 90%.
6 Highlight the other cursor.
7 Move the lower cursor to 0% of
the trace height. A marker is
shown at 10%.
The reading shows the risetime from 10%-90% of the
trace amplitude.
