Digital Readout Oscilloscope: The Digital Readout Oscilloscope instrument has a CRT display and a counter display. The diagram shown is of an instrument where the counter measures the time (Fig. 7.29). The input waveform is…
Storage Oscilloscope (For VLF Signal): Storage Oscilloscope - Storage targets can be distinguished from standard phosphor targets by their ability to retain a waveform pattern for a long time, independent of phosphor peristence. Two storage…
What is Sampling Oscilloscope?: An ordinary Sampling Oscilloscope has a B.W. of 10 MHz. The HF performance can be improved by means of sampling the input waveform and reconstructing its shape from the sample, i.e.…
What is Electronic Switch in Oscilloscope?: The electronic switch is a device that enables two signals to be displayed simultaneously on the screen by a single gun CRT. The basic block diagram of an Electronic…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an electronic switch. There is one…
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 electronic switch which switches two…
High Frequency CRT or Travelling Wave Type CRT: Figure 7.17 illustrates a High Frequency CRT. In an ordinary CRO, there is only one pair of VDPs. When the signal to be displayed is of a…
Delay Line in Triggered Sweep Circuit: Figure 7.13 shows a Delay Line in Triggered Sweep Circuit. Figure 7.14 indicates the amplitude of the signal wrt time and the relative position of the sweep generator output…
Trigger Pulse Generator Circuit: The Trigger Pulse Generator Circuit is activated by signals of a variety of shapes and amplitudes, which are converted to trigger pulses of uniform amplitude for the precision sweep operation. If…
Triggered Sweep CRO: Triggered Sweep CRO - The continuous sweep is of limited use in displaying periodic signals of constant frequency and amplitude. When attempting to display voice or music signals, the pattern falls in…
