Digital Storage Oscilloscope: Block Diagram, Explanation Block Diagram. The block diagram of digital storage oscilloscope is shown in the Fig. Ø The input signal is applied to the amplifier and attenuator section. Ø The oscilloscope uses same type of amplifier and attenuator circuitry as used in the conventional oscilloscopes. CRO - Cathode Ray Oscilloscope Working and Applications Block Diagram of CRO. The following block diagram shows the general purpose CRO contraction. The CRO recruit the cathode ray tube and acts as a heat of the oscilloscope. In an oscilloscope, the CRT produces the electron beam which is accelerated to a high velocity and brings to the focal point on a fluorescent screen.
