Classification and Application of Electronic Measuring Instruments

1

An oscilloscope is an electronic instrument that measures voltage waveforms. It can graphically display the regularity of the measured voltage signal over time. The use of an oscilloscope can not only visually and visually observe the changes in the measured physical quantity, but also can be used to compare the frequency and phase with the waveforms it displays, measure the voltage and current, and trace the characteristics.

2. Signal Generator {TodayHot}

Signal generators (including function generators) provide signal sources for troubleshooting and debugging electronic equipment and instruments. It is an oscillator that produces a certain waveform, frequency, and amplitude. For example: Generate sine wave, square wave, triangle wave, ramp wave and rectangular pulse wave.

3. Transistor characteristics display instrument

Transistor characteristic plotter is a special oscilloscope, which can directly observe various transistor characteristic curves and curvature clusters. For example: the input and output characteristics and feedback characteristics of the three types of transistors: common-emitter, common-base, and common-collector; forward and reverse characteristics of the diode; regulator or Zener characteristics of the Zener diode; it can measure the crystal {HotTag } Breakdown voltage, saturation current, auto or a parameter, etc. of the tube.

4. Infrared tester

Infrared tester is a kind of non-contact temperature measuring instrument, which includes optical system and electronic circuit. After the information is modulated and linearized, it reaches the purpose of indication, display and control. There are two kinds of infrared thermometers, photon temperature measurement and thermal thermometer. They are mainly used for temperature measurement of electric furnaces, crops, railway rails, buried underground ultra-high voltage cable connectors, fire protection, gas analysis, and laser receiving. Control occasions.

5. Integrated circuit tester

This kind of instrument can test the functions and parameters of TI1, PM0S, and CM0S digital integrated circuits. It can also determine the chip type of the erased word and the on-line functional test and online status test of the integrated circuit.

6.LCR parameter tester

Inductance, capacitance, and resistance parameter measuring instruments not only automatically determine the nature of the element, but also display the symbolic pattern and display its value. It can also measure Q, D, Z, Lp, Ls, Cp, Cs, Kp, Ks and other parameters and display the equivalent circuit pattern.

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 analysis signals. You can also test the phone logic and RF circuit signals. For example: control signals of a logic circuit, baseband signals, local oscillator signals of an RF circuit, intermediate frequency signals, transmission signals, and the like.

In addition to the above commonly used electronic measuring instruments, there are time measuring instruments, bridges, phase meters, dynamic analyzers, optical measuring instruments, strain gauges, flow meters, and the like.
