Network analyzer is a comprehensive microwave measurement device that can scan and measure in a wide frequency band to determine network parameters. The device can directly measure the complex scattering parameters of active or passive, reversible or irreversible dual port and single port networks, and provide the amplitude, phase, and frequency characteristics of each scattering parameter in a sweep frequency manner. Mainly used to measure the linear characteristics of radio frequency (RF) components and equipment.

Spectrum tester is a scientific instrument used to decompose complex light into spectral lines. The chemical composition and content of articles can be measured by capturing the optical information by spectrometer. This technology is widely used in the detection of air pollution, water pollution, food hygiene, metal industry and so on.

Spectrum analyzer is a commonly used testing instrument in the field of radio frequency and microwave. Through testing with a spectrograph, important parameters such as signal frequency, signal power, signal bandwidth, and stray performance can be obtained, ensuring that users can always control the interference situation of the equipment and reduce communication failures. Spectral analyzers are currently widely used in wireless device testing, communication testing, electromagnetic radiation monitoring, and other fields.

The constant temperature and humidity test chamber is an instrument and equipment used in laboratories and industrial environments. The device can simulate environments under different climatic conditions to test the performance and stability of products under different temperature and humidity conditions. Widely suitable for use in fields such as medicine, biology, food, cosmetics, etc.

Digital vernier caliper is a precision measuring tool for measuring the length, inner diameter, outer diameter, depth and other values of the workpiece, known as the "industrial eye". Through capacitive grid sensor, digital display vernier caliper can convert mechanical displacement into electrical signal and display it directly, effectively avoiding artificial reading error. It has the characteristics of intuitive reading, convenient use and various functions.

The vibration testing machine is a testing equipment to test whether the product can meet the use requirements under the severe environmental tests such as vibration and impact during its service life. Through the data input and output interface of the equipment, the vibration parameters set by the vibration testing machine host will be transmitted to the vibration controller, so that the vibration table can conduct vibration testing according to the required operating frequency range.

The electronic circuit experiment box is a kind of equipment commonly used in the practical teaching of electronic courses. It is usually composed of an aluminum alloy box, a linear power supply, an experimental circuit board and several electronic components. In teaching, students can either use fixed functional modules to conduct circuit experiments, or build experimental circuits by themselves. Provide students with more opportunities to understand and be familiar with the structure, working principle, key technologies and common measurement methods of electronic circuits, and increase their practical knowledge.
