the screen centerline. It reads zero when the pointer is in the center of the screen.
Auto: The oscilloscope is in the automatic mode and displaying the waveform in the
non-trigger mode.
Trig’d: The oscilloscope has detected a trigger and is collecting the information
generated after the trigger.
Ready: All pre-triggered data have been captured and the oscilloscope is ready to
receive trigger signals.
Scan: The oscilloscope can gather/display the waveform data continuously in scan
mode.
Stop: The oscilloscope has stopped collecting the waveform data.
