rotary control and adjust the trigger level to the roughly
50% of the signal to be measured.

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
rotary control 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 Capturing a Single Signal
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
