Standard Signal Generator Block Diagram and Working Principle: A standard signal generator produces known and controllable voltages. It is used as power source for the measurement of gain, signal to…
What is Digital Storage Oscilloscope (DSO)?: Digital Storage Oscilloscope are available in processing and non-processing types. Processing types include built in computing power, which takes advantage of the fact that…
Applications of Oscilloscope: The range of applications of oscilloscope varies from basic voltage measurements and waveform observation to highly specialized applications in all areas of science, engineering and technology. Voltage…
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…
Spot Wheel Method for Frequency Measurement: As the ratio of the two frequencies being compared increases, the Lissajous pattern becomes more complicated and hence more difficult to interpret. In such…
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…
