Rise Time Measurements
To measure rise time:
1. Push 3 to select CURSOR ON.
2. Push 1 to select (rise time). Observe that two
horizontal cursors are displayed.
3. Push 4 if only one trace is displayed and select
MANUAL or AUTO. AUTO automatically does steps
5 to 7. For two traces, select the required trace A
or B.
4. Use YZ to move the upper cursor to 100% of the
trace height. A marker is shown at 90%.
5. Push 2 to select the other cursor.
6. Use
YZ to move the lower cursor to 0% of the
trace height. A marker is shown at 10%.
The reading now shows the risetime from 10%-90%
of the trace amplitude and the voltage at the cursors
in relation to the zero icon (-).
7. Push 3 to disable the cursors.
