(10) 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, press 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 knob 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 7-3).
