Common electronic measuring instruments

Common electronic measuring instruments Electronic measuring instruments refer to measuring and analyzing instruments using electronic technology, and are a large category of measuring instruments. And with the development of technology, its types are constantly increasing, and the fields of application are also constantly expanding. The following editor will introduce to you what are the common electronic measuring instruments? 1. Oscilloscope Oscilloscope is a common electronic measuring instrument for measuring voltage waveform. Electronic measuring instrument refers to the measurement and analysis instrument using electronic technology. It is a measuring instrument. A large category. And with the development of technology, its types are constantly increasing, and the fields of application are also constantly expanding. The following editor will introduce to you what are the common electronic measuring instruments? 　　1, oscilloscope 　　Oscilloscope is an electronic instrument that measures voltage waveforms. It can graphically display the law of the measured voltage signal over time. Using an oscilloscope can not only visually observe the overall change of the measured physical quantity, but also measure the voltage and current through the displayed waveform, compare the frequency and phase, and draw the characteristic curve.　　2, signal generator 　　 signal generator (including function generator) provides a signal source for repairing and debugging electronic equipment and instruments. It is an oscillator that can generate a certain waveform, frequency and amplitude. For example: generate sine wave, square wave, triangle wave, ramp wave and rectangular pulse wave.　　3, Transistor Characteristic Grapher 　　 Transistor Characteristic Grapher is a special oscilloscope, which can directly observe various transistor characteristic curves and curvature clusters. For example: the input, output characteristics and feedback characteristics of the three connection methods of common emitter, common base and common collection of transistors; forward and reverse characteristics of diodes; voltage stabilization or Zener characteristics of zener tubes; it can measure crystal {HotTag } The breakdown voltage, saturation current, auto-or a parameter of the tube, etc.　　4. Infrared tester 　　 Infrared tester is a non-contact temperature measuring instrument, which includes optical system and electronic circuit, which achieves the purpose of indication, display and control after information is modulated and linearized. At present, there are two types of infrared thermometers in use: photon temperature measurement and thermal temperature measurement. They are mainly used for temperature measurement of electric furnaces, crops, railway rails, deep-buried underground ultra-high voltage cable joints, fire protection, gas analysis, laser reception Control occasions.　　5. Integrated circuit tester 　　 This type of instrument can test the functions and parameters of TI1, PM0S, CM0S digital integrated circuits, as well as determine the chip type to be erased, and perform online function testing and online status testing of integrated circuits.　　6, LCR parameter tester 　　inductance, capacitance, resistance parameter tester, not only can automatically judge the nature of the component, but also can display the symbol graphic and display its value. It can also measure Q, D, Z, Lp, Ls, Cp, Cs, Kp, Ks and other parameters, and display equivalent circuit graphics.　　7, spectrum analyzer 　　 spectrum analyzer has a wide range of applications in frequency domain signal analysis, testing, research, and maintenance. It can measure the amplitude and frequency of the signal at the same time, test and compare the composition of multiple signals and analyze the signal. It can also test mobile phone logic and radio frequency circuit signals. For example: control signal, baseband signal of logic circuit, local oscillator signal, intermediate frequency signal, transmission signal of radio frequency circuit, etc.　　 In addition to the above commonly used electronic measuring instruments, there are also time measuring instruments, bridges, phase meters, dynamic analyzers, optical measuring instruments, strain gauges, flow meters, etc.
