35.3. Example 3: Capture the Single Signal
The digital storage oscilloscope takes the lead in providing the convenience capturing of such non-periodic
signals as pulse and burr, etc. If you intent to capture a single signal, you can not set the trigger level and the
trigger edge unless you have particular priori knowledge of this signal. For example, if the pulse is the logic
signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge
trigger. If it is uncertain as to the signal, you can make an observation of it in advance under the automatic or
ordinary mode to determine the trigger level and the trigger edge.
The operation steps are as follows:
1. Set the probe menu attenuation coefficient to 10X and that of the switch in the probe to 10X (see "6. How
to Set the Probe Attenuation Coefficient" on page 99).
2. Adjust the VOLTS/DIV and SEC/DIV knobs to set up a proper vertical and horizontal ranges for the signal
to be observed.
3. Press the Acquire button to display the Acquire menu.
4. Press the H1 button to display the Acquire Mode menu.
5. Press the F2 button to choose Peak detect.
6. Press the Trigger Menu button to display the Trigger menu.
7. Press the H1 button to display the Trigger Type menu.
8. Press the F1 to choose Single as the type.
9. Turn the M knob to choose Edge as the mode.
10. Press the H2 button to display the Source menu.
11. Press the F1 button to choose CH1 as the source.
12. Press the H3 button to display the Coupling menu; press the F2 button to choose DC as the Coupling.
13. Press the H4 button to choose
14. Rotate the TRIG LEVEL knob and adjust the trigger level to the mid-value of the signal to be measured.
