Abstract:
An oscilloscope intensity regulation apparatus, comprising:cathode ray tube (CRT) means for displaying a wave-form to be observed on a fluorescent screen thereof by means of an electron beam;Z-axis means for delivering a Z-axis output to the CRT so as to obtain the electron beam;a central processing unit (CPU) means for delivering instructions of a value of the Z-axis output to the Z-axis means and of an AGC revision signal indicating a predetermined intensity (B.sub.1) by receiving an intensity input signal;sensing means for sensing the wave-form on the fluorescent screen so as to obtain a sensing output;video means for producing a video signal from the sensing output;automatic gain control (AGC) means for obtaining an amplified video signal of an amplitude regulated by the AGC revision signal so as to procure the predetermined intensity (B.sub.1); anddisplaying means for displaying the wave-form with the predetermined intensity (B.sub.1) in accordance with the amplified video signal.
