Absorbing clamp

The following positioning requirements relating to the absorbing clamp apply.
  • The absorbing clamp is placed around the LUT as shown in Figure 6. The absorbing clamp shall be positioned on the clamp slide with the current transformer facing the EUT.
  • During the clamp scanning, the minimal horizontal distance between the CRP and the SRP shall be (10 ± 1) cm. This distance of 10 cm is required to accommodate different types ofclamps, due to the possible different positions of the CRP. The test results very much depend on this initial position. For reproducibility purposes, it is essential to include this additional specification to ensure that all initial positions can be identical.
  • The EUT shall be keep in the centre of the absorbing clamp at the location of the current transformer, i.e., at the CRP. Most clamps have a centering support for this purpose

  • Slide reference point (SRP):滑轨参考点
  • Clamp reference point (CRP):功率吸收钳参考点
