Abstract
An oscilloscope intensity regulation apparatus is disclosed. The oscilloscope displays wave-forms with the regulated intensity in spite of various wave-form repetition rates or sweep ranges. The scope has a CCD sensor,on a CRT,. The CCD output,is applied to a video circuit,delivering a video signal,. The CPU,instructs an intensity of an electron beam to a Z-axis circuit,and an AGC (automatic gain control) revision signal,to a AGC circuit,in accordance with an intensity input signal,. The AGC circuit,controls its gain for amplifying a video signal,from the CCD,via the video circuit,. When the video signal,is small in its amplitude, the AGC circuit,has a large gain. When the video signal,is large, the circuit,has a small gain. Therefore, an intensity of wave-forms being displayed is regulated in the intensity desired, in spite of various repetition rates of the wave-forms or sweep velocities.
