(8) In the right menu, select Coupling as DC.
(9) In the right menu press Next Page, select Slope as
(10) Turn the Trigger Level knob and adjust the trigger level to the roughly
50% of the signal to be measured.
(11) Check the Trigger State Indicator on the top of the screen, if it is not Ready,
push down the Run/Stop button and start acquiring, wait for trigger to
happen. If a signal reaches to the set trigger level, one sampling will be
made and then displayed in the screen. By using this approach, a random
pulse can be captured easily. For instance, if we want to find a burst burr of
high amplitude, set the trigger level to a slightly higher value of the average
signal level, push the Run/Stop button and wait a trigger. Once there is a
burr occurring, the instrument will trigger automatically and record the
waveform during the period around the trigger time. By turning the
Horizontal Position knob in the horizontal control area in the panel, you
can change the horizontal triggering position to obtain the negative delay,
making an easy observation of the waveform before the burr occurs (see
Figure 6-3).

Example 4: Analyze the Details of a Signal

Noise is very common inside most of the electronic signal. To find out what's
inside the noise and reduce the level of noise is very important function our
oscilloscope is capable to offer.
Noise Analysis
The level of noise sometime indicates a failure of electronic circuit. The Peak
Detect functions acts an important role to help you to find out the details of
