How to measure test repeatability when stability and constant variance are not observed
International Journal of Metrology and Quality Engineering, 2018 Passive intermodulation (PIM) is a critical measurement for radio frequency (RF) communication networks. Yet PIM measurement inherently has very poor repeatability, which makes product assessment unreliable. The RF industry struggles with the issue since
