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. Click the TIME/DIV key to display the rising edge of the waveform.
2. Click the VOLTS and Vertical Position keys to adjust the waveform amplitude to about 5
divisions.
3. Push the CH1 MENU button.
4. Push the VOLTS option button and select Fine. Click the Vertical Position key to accurately
separate the waveform into 5 divisions.
5. Click the Vertical Positon key 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 place it at the 10% level of the waveform.
9. Select Cursor E and 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.
