Measuring Rise Time - Tektronix TPS2000 Series User Manual

Measuring Rise Time

After measuring the pulse width, you decide that you need to check
the rise time of the pulse. Typically, you measure rise time between
the 10% and 90% levels of the waveform. To measure the rise time,
follow these steps:
1. Turn the SEC/DIV knob to display the rising edge of the
waveform.
2. Turn the VOLTS/DIV and VERTICAL POSITION knobs to set
the waveform amplitude to about five divisions.
3. Push the CH 1 MENU button.
4. Push Volts/Div
5. Turn the VOLTS/DIV knob to set the waveform amplitude to
exactly five divisions.
6. Turn the VERTICAL POSITION knob to center the waveform;
position the baseline of the waveform 2.5 divisions below the
center graticule.
7. Push the CURSOR button to see the Cursor Menu.
8. Push Type
9. Push Source
10. Push the Cursor 1 option button.
11. Turn the multipurpose knob to place a cursor at the point where
the waveform crosses the second graticule line below center
screen. This is the 10% level of the waveform.
