12. If the Trigger State Indicator at the top of the screen does not indicate Ready, push down the
RUN/STOP button and start Acquire, waiting the emergence of the signal in conformity with the trigger
conditions. If a signal reaches to the set trigger level, one sampling will be made and then displayed in the
screen. With this function, any random occurrence can be captured easily. Taking the burst burr of larger
amplitude for example, set the trigger level to the value just greater than the normal signal level, and then
presses the RUN/STOP button and waits. When there is a burr occurring, the instrument will trigger
automatically and record the wave form generated during the period around the trigger time. With the
HORIZONTAL POSITION knob in the horizontal control area in the panel rotated, you can change the
horizontal position of the trigger position to obtain the negative delay, making an easy observation of the
waveform before the burr occurs (see Fig. 106).
Example 4: Analyze the Details of a Signal
Observe the Signal Containing Noises
If the signal is interfered by the noise, the noise may cause a failure in the circuit. For the analyzing of the
noise in detail, please operate the instrument according to the following steps:
1. Press the ACQUIRE button to display the ACQU MODE menu.
2. Press the F2 menu selection button and choose Peak Detect.
In this case, the screen display contains the wave form of a random noise. Especially when the time base is
set as Low Speed, then noise peak and burr contained in the signal can be observed with the peak detection
(See Fig. 107).
