The trigger determines when the scopebox starts to acquire data and display a
waveform. When a trigger is set up properly, it can convert unstable displays or
blank screens into meaningful waveforms.
When the scopebox starts to acquire a waveform, it collects enough data so
that it can draw the waveform to the left of the trigger point. The scopebox
continues to acquire data while waiting for the trigger condition to occur. After it
detects a trigger, the scopebox continues to acquire enough data so that it can
draw the waveform to the right of the trigger point.
User can make some settings directly by tapping < or > next to options. See
Fig. 3-4.
