美军标MIL-STD-883K中噪声容限测试方法的适用性研究

Study on the applicability of test methodof noise margin in U.S.military standardMIL-STD-883K

提出了美军标MIL-STD-883K噪声容限测试方法在使用中的一些问题。基于对业界所用噪声容限测试方法的分析,比较了各种方法间的区别和优缺点,分析了美军标中噪声容限测试方法很少修订却长期存在的原因。通过对相关标准和测试方法的梳理,明确了美军标及其他噪声容限测试方法的适用范围,提出了我国相应标准制修订方向的建议。测试结果表明,最大乘积法和动态最大等边法在较大的范围内都适用,可以在我国相应标准中加以采用。

This paper presents some problems of noise margin test methodin the MIL-STD-883K use. Based on the analysis of the noise margin test methods used in the industry, the differences, advantages and disadvantages of the methods are compared. Analyzing the reason why noise margin test in the standard method is rarely revised, the paper proposes the applicability of the noise margin test methods in MIL-STD-883K and the industry, and revision directionsforour corresponding standard in China. The test results show that maximum product criteria and dynamic maximum equal criteria are applicable in a wide range, and can be used in the corresponding standards in China.
