Oscilloscope Operating Precautions: In addition to the general safety precautions, the following specific precautions should be observed when operating any type of oscilloscope. Most of the Oscilloscope Operating Precautions also apply to recorders. Always study…
Fibre Optic CRT Recording Oscilloscope: Fibre Optic CRT Recording Oscilloscope - The familiar CRT oscilloscope has an extremely HF response, but permanent records, normally photography of the screen, cannot be taken, since they are time…
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 all data is already in…
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 Measurements: The most direct 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 compensated RC attenuator is required…
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 convenient lengths of wire for…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive balances of the bridge. Figure…
Measure of Capacitance and Inductance in Oscilloscope: Measure of Capacitance and Inductance in Oscilloscope - Capacitance may be measured from a capacitor discharge curve. This requires a dc oscilloscope with a triggered single sweep that…
Setup for Diode Testing in Oscilloscope: Diode Testing in Oscilloscope -The voltage-current characteristics curve of a crystal diode may be observed using the circuit given in Fig. 7.37 (a). In this case the internal sweep…
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 ring pattern in place of…
