4.
Use the oscilloscope measurement capability to calculate and
display rise time. Rise time is determined from the 10% and 90%
amplitude points on the waveform. Record the rise time as
t
s.
The system rise time ( t
s
) that you measured in step 4 represents the
rise time of the test system without the probe.
The following steps instruct you to assemble the test system that
includes the probe, as shown in Figure 15. The system and probe rise
time (
t
s+p
) that you measure in step 8 is used to calculate the probe
rise time ( t
p
) in step 9.

Adjust the oscilloscope horizontal and vertical position controls
to display a signal similar to that shown in Figure 15.
