Operating Your Oscilloscope
To make time measurements automatically
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, 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, the maximum and minimum levels
are used to calculate the 10% and 90% points. These levels are shown on
page 2-19 in figures 2-8 and 2-9.
