Abstract: The detection of radiated disturbance of electronic products has a significant role in promoting the progress and development of related industries. Different test tables will not have the same impact on the test results. To obtain accurate test results, comparisons can only be made in a uniform interval. The results are unified with the test data of the test table, so that it can be effective. Get fit with the actual test results. The choice of materials for the test table will have a greater impact on the test. At the same time, due to the test process, the relevant equipment will also emit radiation, which has an impact on the data and collection of the test. Therefore, the selected material must have insulation. This can effectively avoid the interference of electrical ions, and its related materials must be easily collected and widely used in social life. This result has a reference value for real life. - 1 - Why did you choose wood and polystyrene foam for comparison 1.1 Wood Products Since China has a tradition of using wood products since ancient times, the degree of familiarity and recognition of this material is the highest. Since wood products are widely used in various sectors of society in the real society, they are representative. Other materials products, such as metal products, are inherently well-conducted, malleable, and easily conductive, and have a significant impact on the results during the radiation disturbance detection process. They cannot provide us with valid data. Conduct the study and therefore do not choose. 1.2 Polystyrene foam Polystyrene foam is a white object that contains a volatile liquid foaming agent and is heated to form a structure rich in closed bubbles. It does not have its own conductivity, its own application range is also more extensive, selection of materials is more common. As this is a new type of multi-purpose material, the use of its finished products is relatively mature, and the most important is that its test results for radiation disturbance are more real, there is no big deviation, and can be used as a basis, so take this Materials for experimentation. - 2 - Analysis of test results of radiation disturbance of electronic products with test tables of related materials under darkroom conditions Since the second test took two frequency bands to test the test tables of two materials, it is divided into two parts for discussion here. 2.1 30MHz-1GHz test results analysis By collating and comparing the results of the test results in the 30 MHz-1GHz interval, the following conclusions can be drawn: (1) In the same test frequency range, the test results of the polystyrene foam test table are relatively high compared with the test results curve obtained without the test table, and there are only some deviations in the individual frequency bands; the wood test The test results of the table and the non-test table show that the curve has a high degree of coincidence in the frequency range of 30 MHz to 90 MHz, and the deviation in the rest of the remaining frequency bands is larger. (2) Within the range of 30 MHz to 1 GHz frequency test, the absolute value of the difference between the polystyrene foam test table and the non-test table is less than 2 dB, and the absolute value of the maximum frequency difference is the same; The difference between the absolute value of the test results of the wooden test table and the non-test table in the frequency band of 200MHz to 650MHz is more obvious, and the absolute value of the maximum difference frequency is 540MHz, and the value is 5.66dB. In the frequency band of 860MHz to 1GHz, the absolute value of the resulting difference is greater than 2dB. Therefore, it is not difficult to draw conclusions from the above test results that in the radiation disturbance frequency range of 30MHz-1GHz, the impact of the polystyrene foam test table on the results of the radiation disturbance test is much smaller than that of the wooden test table. As a result, the comparative tests have verified that the polystyrene foam test table has unparalleled advantages over the wooden test table. 2.2 Analysis of Test Results in 1GHz-8GHz Interval The test results in this section are compared and analyzed. The relative data values ​​are compared with those without the test table. The main results are as follows. (1) In the standard test frequency range, the polystyrene foam table data has a relatively high degree of agreement with the test table test result curve, and its consistent coverage is more prevalent in the entire range; and the wooden test table The test results are inconsistent with the curve of test results without test table, and the degree of deviation is large, especially in the frequency range of 1GHz-2.7GHz. (2) Under the data comparison of the entire 1 GHz to 8 GHz frequency test range, it can be seen that the absolute value of the effective difference between the majority of the polystyrene foam table and the test result without the test table is less than 2 dB. However, the results are more than 2dB at both frequency points of 2.3GHz and 2.7GHz, and thus show a difference in this interval, and the overall degree of agreement is relatively high. The absolute value of the difference between the test results of the wooden test table and the test results without the test table in the frequency band from 1 GHz to 2.7 GHz is more obvious, especially at 1 GHz, which is the maximum frequency. The absolute value of the measured difference in the 6GHz to 8GHz band is greater than 2dB. There is a big difference in the degree of similarity between it and the non-test table, which can be clearly seen. Through comprehensive analysis of the results obtained from the above tests, the following conclusions can be drawn: Test results conducted in the frequency range of 1 GHz to 8 GHz indicate that the impact of the polystyrene foam test table on the results of the radiation disturbance test is much smaller than that of the wooden test. Table, which from the data to verify the polystyrene foam test table in the test results compared to the wooden test table has a clear advantage. - 3- to sum up In summary, through the comparative analysis of the comprehensive data of the test results in the two frequency bands of the 30 MHz-1 GHz frequency band and the 1 GHz-8 GHz frequency band, it can be concluded that the overall impact of the wooden test table and the radiated disturbance test results is relatively large. The overall test data of the polystyrene foam test table is more rigorous and superior to the data of the wooden test table, and has obvious advantages for the wooden test table. At the same time, the polystyrene foam test table has better moisture resistance, electrical insulation and stability due to its own characteristics. Of course, due to factors such as the operation of relevant personnel during the experimental process, it will also have a significant impact on the experimental data. Therefore, the test results must be fully considered to ensure that the data can be applied to the actual situation.
