Characterisation of a model reverberation chamber for electromagnetic emission measurements
Electromagnetic emission from devices must be kept below certain limit values to guarantee compatible systems without interference. To achieve this the emission must be measured, and 'reverberation chambers' can be used for this task.
In this project a model reverberation shall be evaluated against the performance criteria of an international standard (IEC 61000-4-21), and the effect of different tuner designs be investigated. This will require S-parameter measurements up to 2 GHz, and the development of MATLAB scripts for obtaining, processing and presenting multi-dimensional data.
Comparison of radiated emission measurements according to CISPR 16 and MIL-STD 461
Electromagnetic emission from devices must be measured to establish compliance with relevant standards. Two commonly used standards are CISPR 16 for commercial products, and MIL-STD 461 for military applications. Both test methods are different in respect to antenna type (biconical vs. horn antenna), measurement distance (1 m vs. 3 or 10 m) and detector (Peak detector vs. Quasi-Peak detector).
In this project emission measurements shall be made in ICRAR's anechoic chamber against both methods, results be compared, and differences be explained. Of particular interest is the question, for what kind of source devices measurement results cannot be converted between the two methods.
