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 101).
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
(rising
)
as the Slope.
14. Rotate the
TRIG LEVEL
knob and adjust the trigger level to the mid-value of the signal to be measured.
