摘　　要：分析了GJB 151B-2013 CS101、CS106、CS114和CS116试验电平施加的共同特点,即其施加电平都需要在校验值和监测值之间进行动态比较;用电路理论说明了由于校验电路所用负载和实际测试负载不同,导致按校验文件注入信号时实际监测电平与校验值可能有很大的差别。严格按照GJB 151B-2013规定的测试方法可以避免过测试。This paper analyzes the common characteristic of GJB 151B-2013 CS101,CS106,CS114 and CS116 when testing levels are applied to,that is the applied levels need a dynamic comparison between the calibration value and the monitored value,explain with the circuit theory that the difference between the calibration value and the actual monitoring level may be very obvious when the calibration file is used to control the actual injected signal due to the difference between the load used in the calibration circuit and the actual test load.The conclusion is drawn that over-testing can be avoided by using standardized testing methods of GJB 151B-2013.
