Double Beam Oscilloscope

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

Sampling Oscilloscope

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 t

Digital Storage 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 ge

Lissajous Patterns of CRO or Cathode Ray Oscilloscope

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 plate

Strain Gauge: Working Principle & Diagram

What is a Strain Gauge A 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 mea

Oscillator Transducer: What is it? (Advantages & Disadvantages)

What is an Oscillator Transducer An 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 cali

Inductive Transducers

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 voltage

Temperature Transducers: What Are They? (Types & Examples)

What is a Temperature Transducer? A Temperature Transducer is a device that converts the thermal quantity into any physical quantity such as mechanical energy, pressure and electrical signals etc. For example, in a thermocouple the electrical potential difference is produced due to temperature diffe
