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 press the
RUN/STOP
button and
wait. 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. 58).

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.
Noises Analysis
The level of noise sometime indicates a failure of electronic circuit. The
