Attenuators: Attenuators are designed to change the magnitude of the input signal seen at the input stage, while presenting a constant impedance on all ranges at the attenuator input. A…

Probes for CRO: Direct Probes (1 : 1): The simplest types of Probes for CRO (one can hardly call it a probe) is the test lead. Test leads are simply…

Gear Wheel Method for Frequency Measurement: When a Lissajous figure contains a large number of loops, accurate counting becomes difficult. Figure 7.35 shows a test method that uses a modulated…

Frequency Measurement by Lissajous Method: The oscilloscope is a sensitive indicator for frequency and phase measurements. This Frequency Measurement by Lissajous Method techniques used are simple and dependable, and measurement…

Dual Beam CRO Block Diagram and Working Principle: Figure 7.18 illustrates a block diagram of a Dual Beam CRO. The dual trace oscilloscope has one cathode ray gun, and an…

Vertical Amplifier: The sensitivity (gain) and frequency bandwidth (B.W.) response characteristics of the oscilloscope are mainly determined by the vertical amplifier. Since the gain B.W. product is constant, to obtain…

What is the Principle of Sweep Generator?: Principle of Sweep Generator : The amplitude of a voltage may be directly measured on a calibrated viewing screen from the length of…
