CISPR 16-1-3:2004+A1:2016+A2:2020被指定为基本标准，它规定了用于测量30 MHz至1 GHz频率范围内无线电干扰功率的吸收钳的特性和校准。这第二版取消并取代了2003年出版的第一版。它构成技术修订。在本版中，指定了吸收夹的更详细的校准方法。此外，还介绍了新的替代校准方法，这些方法比先前指定的方法更实用。定义了描述吸收钳的附加参数，如宽带吸收器的去耦因子（DF）和电流互感器的去耦因子（DR），以及它们的验证方法。吸收夹试验部位（ACTS）的确认程序也包含在文件中。2006年2月更正的内容已列入本副本。该合并版本由第二版（2004年）、修正案1（2016年）和修正案2（2020年）组成。因此，除了本出版物之外，没有必要下令进行修订。

CISPR 16-1-3:2004+A1:2016+A2:2020 is designated a basic standard, which specifies the characteristics and calibration of the absorbing clamp for the measurement of radio disturbance power in the frequency range 30 MHz to 1 GHz. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. In this edition a more detailed calibration method for the absorbing clamp is specified. Furthermore, new alternative calibration methods are introduced which are more practicable than the one which was specified previously. Additional parameters to describe the absorbing clamp are defined, like the decoupling factor for the broadband absorber (DF) and the decoupling factor for the current transformer (DR), along with their validation methods. A procedure for the validation of the absorbing clamp test site (ACTS) is also included in the of the absorbing clamp test site (ACTS) is also included in the document. The contents of the corrigendum of February 2006 have been included in this copy. This consolidated version consists of the second edition (2004), its amendment 1 (2016) and its amendment 2 (2020). Therefore, no need to order amendments in addition to this publication.
