Oscilloscopes are an incredibly useful tool of the electronics world after a multimeter. Without a scope, it’s quite difficult to know what is happening in a circuit. But this type of test equipment has its own limitation. To overcome this limitation, one must understand the weakest links in the system fully and compensate for that in the best way possible.The important feature of the oscilloscope is the bandwidth. How fast the number of analog sample per second that it can read is the key facto

Normally, an oscilloscope is an important tool in an electrical field which is used to display the graph of an electrical signal as it varies with respect to time. But some of the scopes have additional features apart from their fundamental use. Many oscilloscopes have the measurement tool that help us to measure waveform characteristics like frequency, voltage, amplitude, and many more features with accuracy. Generally, a scope can measure time-based as well as voltage-based characteristics.Vol

The dual beam oscilloscope emits two electron beams that are displayed simultaneously on a single scope, which could be individually or jointly controlled. The construction and working of the dual beam oscilloscope are completely different from dual trace oscilloscope. The tubes are more complicated to build, and the whole thing is more expensive.A special type of double beam oscilloscope can display two electrons beam by generating or deflecting beams. Now a days, double beam oscilloscope is ou

Before discussing sampling oscilloscope, we must know the basic principle and functioning of an ordinary oscilloscope. It is an instrument which receives one or more electrical signals and then produces the waveform on the screen simultaneously. The sampling oscilloscope is an advanced version of the digital oscilloscope with some added features and uses for the special purpose.It is designed to provide a very high-frequency function by sampling several wave forms successively. Such oscilloscope

A digital oscilloscope is an instrument which stores a digital copy of the waveform in the digital memory which it analyses further using digital signal processing techniques rather than using analogue techniques. It captures the non-repetitive signals and displays it consciously until the device gets reset. In digital storage oscilloscope, signals are received, stored and then displayed. The maximum frequency measured by digital oscilloscope depends upon two things: one is sampling rate of the

Cathode Ray Oscilloscope (CRO) is very important electronic device. CRO is very useful to analyze the voltage wave form of different signals. The main part of CRO is CRT (Cathode Ray Tube). A simple CRT is shown in figure below-When both pairs of the deflection plates (horizontal deflection plates and vertical deflection plates) of CRO (Cathode Ray Oscilloscope) are connected to two sinusoidal voltages, the patterns appear at CRO screen are called the Lissajous pattern.Shape of these Lissajous p

What is a Cathode Ray Oscilloscope?A Cathode Ray Oscilloscope (CRO) is an instrument generally used in a laboratory to display, measure and analyze various waveforms of electrical circuits. A cathode ray oscilloscope is a very fast X-Y plotter that can display an input signal versus time or another signal.Cathode ray oscilloscopes use luminous spots which are produced by striking the beam of electrons and this luminous spot moves in response variation in the input quantity. At this moment one qu

What is a Strain GaugeA strain gauge is a resistor used to measure strain on an object. When an external force is applied on an object, due to which there is a deformation occurs in the shape of the object. This deformation in the shape is both compressive or tensile is called strain, and it is measured by the strain gauge. When an object deforms within the limit of elasticity, either it becomes narrower and longer or it become shorter and broadens. As a result of it, there is a change in resist

What is an Oscillator TransducerAn oscillator transducer is a type of transducer that can be used to measure force, pressure, or displacement by converting it a voltage, which can then be measured by a voltmeter. Oscillator transducer are mostly used as secondary transducers, with their output calibrated in terms of their input quantity. Oscillatory transducer consists of following parts Mechanical linkage Oscillator Frequency modulator Force summing memberMechanical linkage: This is used to lin

Inductive transducers work on the principle of inductance change due to any appreciable change in the quantity to be measured i.e. measured. For example, LVDT, a kind of inductive transducers, measures displacement in terms of voltage difference between its two secondary voltages. Secondary voltages are nothing but the result of induction due to the flux change in the secondary coil with the displacement of the iron bar. Anyway, LVDT is discussed here briefly to explain the principle of inductiv
