average value, “Vp” is the peak-peak value and “Vk” is the root-mean-
square value
3. Auto measurement screen No. 2
4. Horizontal triggering position
5. The difference in time between the horizontal triggering position and the
screen’s centerline (zero when the pointer is in the center of the screen)
6. The
trigger

ready to receive trigger signals
Scan:
The oscilloscope records and displays waveform data continuously
Stop:
The oscilloscope has stopped collecting waveform data
7. Red and blue trigger pointer shows vertical position of alternate triggers.
