To make time measurements automatically

You can measure the following time parameters with the oscilloscope:

frequency, period, duty cycle, width, rise time, and fall time. The following

exercise guides you through the Time keys by making a rise time

measurement. Figure 2-6 shows a pulse with some of the time measurement

points.

Connect a signal to the oscilloscope and obtain a stable display.

When the signal has a well-defined top and bottom (see figure 2-8), the rise

time and fall time measurements are made at the 10% and 90% levels. If the

oscilloscope cannot find a well-defined top or bottom (see figure 2-9), the

maximum and minimum levels are used to calculate the 10% and 90% points.
