(9) Select Mode&HoldOff in the bottom menu; select Single in the right
menu.
(10) Adjust the trigger level to the roughly 50% of the signal to be measured,
you can use the TRIG LEVEL knob or the touchscreen (see
"Vertikalsystem per Touchscreen" on P21).
(11) 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 0-3).
