| Abstract: | An accurate microwave attenuation measurement system developed by Beijing Institute of Radio Metrology and Measurement based on IF(Intermediate Frequency) series substitution method is described in this paper.This system employs an Aemi-automated Inductive Voltage Divider(IVD) as a reference standard.And it is greatly improving the measurement accuracy.The Semi-automated inductive voltage divider,experimental measurement system,measurement results and further improvement is discussed in detail.This system can perform accurate measurement from 10MHz to 18GHz covering the attenuation range of 80dB. |
