Measuring Rise Time of Pulse
You may need to measure the rise time of the pulse in many application environments, usually, to
measure the rise time between the 10% and 90% levels of the pulse waveform. To do so, follow
the steps below.
1. Turn the SEC/DIV knob to display the rising edge of the waveform.
2. Turn the VOLTS/DIV and VERTICAL POSITION knobs to adjust the waveform amplitude to
about 5 divisions.
3. Push the CH1 MENU button.
4. Push the VOLTS/DIV option button and select Fine. Turn the VERTICAL POSITION knob to
accurately separate the waveform into 5 divisions.
5. Turn the VERTICAL POSITION knob to center the waveform. Position the waveform baseline
to 2.5 divisions below the center graticule.
6. Press the CURSOR button.
7. Push the Type option button and select Time. Push the Source option button to select CH1.
8. Select Cursor S and turn V0 to place it at the 10% level of the waveform.
9. Select Cursor E and turn V0 to place it at the 90% level of the waveform.
10. The Delta readout in the Cursor Menu is the rise time of the pulse.
See the figure below for better understanding.
