标准摘要
[中文适用范围]： IEC 61280 的这一部分规定了通过加速测量来确定低 BER 值的两种主要方法。其中包括可变决策阈值方法（第 4 条）和可变光学阈值方法（第 5 条）。此外，附件 B 中描述了第三种方法，即正弦干扰法。 [外文原描述]： IEC 61280-2-8:2003 specifies two main methods for the determination of low BER values by making accelerated measurements. These include the variable decision threshold method (Clause 4) and the variable optical threshold method (Clause 5). In addition, a third method, the sinusoidal interference method, is described in Annex B. Key Words: BER values, variable decision threshold method, variable optical threshold method, sinusoidal interference method
