Classification of several major electronic measuring instruments and their applications
Classification of several major electronic measuring instruments and their applications An 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, you can not only visually and visually observe the changes in the measured physical quantity, but also use the waveforms it displays, measure voltage and current, compare frequency and phase, and plot characteristic curves. 2. Signal generator Signal generators (including function generators) provide a source for servicing and debugging electronics and instruments. It is an oscillator that produces a certain waveform, frequency and amplitude. For example, sine waves, square waves, triangle waves, ramp waves, and rectangular pulse waves are generated. 3. Transistor characteristic diagram The transistor characteristic plotter is a dedicated oscilloscope that directly observes various transistor characteristic curves and musical clusters. For example: transistor common-emitter, common-base and common-collection input and output characteristics and feedback characteristics; diode forward and reverse characteristics; voltage regulator or Zener characteristics; it can measure transistor blow Wear voltage, saturation current, self or a parameter. 4. Infrared tester The infrared tester is a non-contact temperature measuring instrument, which includes an optical system and an electronic circuit, and achieves the purpose of indication, display and control after modulating and linearizing the information. At present, the infrared thermometers have two kinds of photon temperature measurement and thermal thermometers, which are mainly used for temperature measurement of electric furnaces, crops, railway rails, deep underground high-voltage cable joints, fire protection, gas analysis, laser receiving, etc. Control the occasion. 5. Integrated circuit tester This type of instrument can test the functions and parameters of TI1, PM0S, CM0S digital integrated circuits, and can also judge the chip type of erased words and online functional test and online state test of integrated circuits. 6.LCR parameter tester The inductance, capacitance, and resistance parameter measuring instrument can not only automatically judge the nature of the component, but also display the symbol graphic and display its value. It can also measure parameters such as Q, D, Z, Lp, Ls, Cp, Cs, Kp, Ks, and display equivalent circuit patterns. 7. Spectrum Analyzer Spectrum analyzers have 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, and test the composition of the multi-channel signal and the analysis signal. You can also test the signal of the phone logic and RF circuits. For example: the control signal of the logic circuit, the baseband signal, the local oscillator signal of the radio frequency circuit, the intermediate frequency signal, the transmission signal, 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.
