(14) Rotate the TRIG LEVEL knob and adjust the trigger level to the mid-value of
the signal to be measured.
(15) If the Trigger State Indicator at the top of the screen does not indicate Ready,
push down the Run/Stop button and start acquiring, 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 waveform 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.6-3).
