Abstract

This paper deals with the experimental characterization of an accurate phase measurement system using transmission lines as phase reference. In particular, the used prototype implementing the accurate phase measurement system is also described. The prototype characterization aims of assessing the repeatability of the phase measurement and identifying the systematic effects affecting them. Several transmission lines, priory characterized by means of a Vector Network Analyzer, have been used as phase references. The obtained results demonstrated the standard deviation increases with the sine-wave frequency, while systematic effects are clearly visible at 10 kHz and 100 kHz. The maximum obtained standard deviation at 10 MHz is 0.30 ◦ .
