电参数测量中线性滤波器的应用分析

Application Analysis of the Linear Filter in the Electrical Parameter Measurement

照明产品检测中,对产品进行电参数测试时,功率分析仪需不需要开启线性滤波器,以及如果需要开启,截止频率应该设置多少比较合理,在行业内一直都存在不同的看法。本文通过实际的测试数据、标准要求等方面对这个问题进行分析,从而给出最终的分析结果。确保照明产品检测人员及照明企业在对照明产品进行电参数测试时,能够正确地选择线性滤波器的开启或关断。同时,也有助于为照明产品电子线路设计人员提供电子电路设计指导。

In the testing of lighting products,does the power analyzer need to turn on the linear filter when testing the electrical parameters of the product?If it needs to be turned on,how much should the cut-off frequency be set reasonably?There have always been different opinions within the industry.This paper analyzes this problem through the actual test data,standard requirements and other aspects,so as to give the final analysis result,to ensure that lighting product inspection personnel and lighting companies can correctly select the linear filter on or off when testing the electrical parameters of lighting products.At the same time,it also helps to provide electronic circuit design guidance for lighting product electronic circuit designers.
