Evaluation on uncertainty of noise parameter against commercial measurement

This paper starts the work of evaluation on uncertainty of noise parameters against commercial measurement system built by PNA-X VAN from Agilent and Tuner from Maury, analyzes the input and output data of the measurement system, builds measurement model, designs the method of uncertainty evaluation that can meet requirement of international standard ISO/IEC98-3, develops simulation software and gets four uncertainty data of noise parameter. Through the comparing measurement with same type of system from Agilent and Tsinghua University, it is proved that the uncertainty evaluation data is reasonable and valid.
