Description
Summary:In this paper, vectorial network analyzer (VNA) based measurements of Passive Intermodulation (PIM) were presented. The PIM measurement system was established as a part of the EMPIR JRP FutureCom project. A modified calibration model was introduced for calibrating the PIM measurement system using a 'Without Thru' calibration algorithm. The uncertainty contributors were identified and evaluated. Two PIM standards from Rosenberger with a 4.3-10 connector type were employed for PIM measurement with uncertainty at different PIM levels using this vectorial PIM System. The measurement uncertainty was calculated, and it is 0.43{{\;dB}} \& 2.3{{\;dB}} for the measured PIM levels - 76.25\text{dBm} \& −114.72 dBm, respectively. The uncertainty budget was also calculated and reported in this work.
