VECTOR NETWORK ANALYSIS UNCERTAINTY EVALUATION FOR ONE-PORT MEASUREMENTS
Harald Jaeger · 2010
Vector Network Analyzers (VNA) are frequently used in calibration laboratories or in production lines, for instance. Their versatility and expressive means of presenting the measurement results make them an ideal partner for numerous applications. But when it comes to qualify a measurement result the related measurement uncertainties are of great importance, if not mandatory. Finally traceability of the measurement needs to be achieved. However, determining the related measurement uncertainties can get out of hands quickly: the math behind the vector error correction is quite demanding and the number of input quantities high, sometimes overwhelming. Understanding the significant influences helps avoiding errors, to improve the measurement procedures and to keep the math downt oearth.
