9.Demonstration
(9) Select Coupling in the bottom menu. Select DC in the right menu.
(10) In the bottom menu, select Slope as (rising).
(11) Turn the Trigger Level knob and adjust the trigger level to the roughly 50% of
the signal to be measured.
(12) 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 9-3).

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 these noise. Here
is how we do it:
