Measurement
A rise time measurement is the time duration measurement that is
made between the 10% and 90% points on the leading edge of a
waveform (see Figure 3-5). The fall time is measured between
90% and 10% points on the trailing edge of a waveform.

To measure the rise time of a waveform, you can use the following
procedure:
Step
1.
Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Apply a signal with an amplitude of exact five-divisions
to either vertical channel input connector and set the
Vertical MODE to display the channel used.
Step 3. Adjust the Trigger LEVEL control to obtain a stable
display.
