At present, the Chinese economy is in the stage of industrial upgrading and independent innovation. China's electronic measuring instrument industry will usher in the second opportunity for development since the founding of New China. An industry from the selection of raw materials, production process monitoring, product testing, industry operations require electronic measuring instruments to complete, electronic measurement equipment shoulders the industrial mission of upgrading and independent innovation in other industries.

Electronic measuring instruments have a unique relevance strategy. Its own development is of great importance to the development of the entire national economy, especially the electronic information industry. Independently developing high-end electronic measuring instruments is the right choice for countries and enterprises. In the next few years, under the strong driving force of synthetic instruments, SDR (software-defined radio) measurement instruments and multi-field instrument interoperability will become hot spots. In the space of LXI and USB link bus, electronic measurement instrument industry will achieve more technological innovations. , and form positive interaction with the development of electronic devices and electronic applications. At present, the domestic demand for electronic measuring instruments is very strong. The market size will reach about 10 billion yuan, and the sales volume will be more than 700 million units. The growth rate will reach more than 20%.

According to the function of measuring instruments, electronic measuring instruments can be divided into two categories: special purpose and general purpose. Dedicated electronic measuring instruments are specially designed for specific purposes and are suitable for the measurement of specific objects. For example, optical fiber test instruments are used to test the characteristics of optical fibers. Communication test instruments are used to test parameters in communication lines and communication processes. Universal electronic measuring instruments are designed to measure one or a few basic electrical parameters and are suitable for a variety of electronic measurements.

General electronic measuring instruments can be subdivided into the following categories according to their functions:

1 signal generator: used to provide a variety of measurements required signal, depending on the use, but also have different waveforms, different frequency range and various power signal generator, such as low frequency signal generator, high frequency signal generator, function Signal generators, pulse signal generators, arbitrary waveform signal generators, and radio frequency synthesis signal generators.

2 voltage measuring instruments: used to measure the electrical signal voltage, current, level and other parameters, such as ammeter, voltmeter (including analog voltmeter and digital voltmeter), level meters, multimeters and so on.

3 frequency, time measuring instruments: used to measure the electrical signal frequency, time interval and phase parameters such as various frequency meter, phase meter, wavelength meter, and various time and frequency standards.

4 signal analysis instruments: used to observe, analyze and record the changes of various electrical signals, such as various oscilloscopes (including analog oscilloscopes and digital oscilloscopes), waveform analyzers, distortion analyzers, harmonic analyzers, spectrum analyzers and Logic analyzer and so on.

5 electronic components test equipment: used to measure the electrical parameters of a variety of electronic components, testing whether it meets the requirements. According to the different test objects, it can be divided into transistor tester (such as transistor characteristic plotter), integrated circuit (analog, digital) tester, and circuit component (such as resistance, inductance, capacitance) tester (such as universal bridge and High-frequency Q table) and so on.

6 Electric wave characteristic tester: It is used to measure parameters such as radio wave propagation and interference intensity, such as test receiver, field strength meter, interference tester and so on.

7 network characteristics test equipment: used to measure the frequency characteristics of the electrical network, impedance characteristics, power characteristics, such as impedance tester, frequency characteristics tester (also known as scanners), network analyzers and noise figure analyzers.

8 Auxiliary instruments: instruments used in conjunction with the above-mentioned various instruments, such as various types of amplifiers, attenuators, filters, recorders, and a variety of AC and DC power supplies.
