Trigger Controls
The trigger determines when the oscilloscope starts to obtain data and display a
waveform. When the trigger is set up correctly, it can convert unstable displays or
blank screens into meaningful waveforms. The oscilloscope acquires data while
waiting for the trigger condition to occur. After it detects a trigger, the
oscilloscope continues to obtain enough data so it can draw the waveform on the
display.
