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.

Key words: Attenuation measurement, IF substitution, Semi-automated Inductive Voltage Divider, Electro Magnetic Compatibility
