15. If the Trigger State Indicator at the top of the screen does not indicate Ready, push down the Run/Stop<br />
button and start acquiring, waiting the emergence of the signal in conformity with the trigger conditions. If<br />
a signal reaches to the set trigger level, one sampling will be made and then displayed in the screen. With<br />
this function, any random occurrence can be captured easily. Taking the burst burr of larger amplitude for<br />
example, set the trigger level to the value just greater than the normal signal level, and then presses the<br />
Run/Stop button and waits. When there is a burr occurring, the instrument will trigger automatically and<br />
record the waveform generated during the period around the trigger time. With the HORIZONTAL<br />
POSITION knob in the horizontal control area in the panel rotated, you can change the horizontal position<br />
of the trigger position to obtain the negative delay, making an easy observation of the waveform before<br />
the burr occurs (see Fig. 80).<br />

35.4. Example 4: Analyze the Details of a Signal<br />
Observe the Signal Containing Noises<br />
If the signal is interfered by the noise, the noise may cause a failure in the circuit. For the analyzing of the<br />
noise in detail, please operate the instrument according to the following steps:<br />
1. Press the Acquire button to display the Acquire menu.<br />
2. Press the H1 button to display ACQU Mode menu.<br />
3. Press the F2 button to choose Peak detect.<br />
In this case, the screen display contains the waveform of a random noise. Especially when the time base is set<br />
as Low Speed, then noise peak and burr contained in the signal can be observed with the peak detection (see<br />
Fig. 81).<br />
