The performance is characterized by conducted measurements and verified by over-the-air measurements, which confirm the sensitivity and highlight the temporal resolution of the setup. Dynamic range, maximum measurable path loss and phase stability are evaluated. The results show that the performance in terms of dynamic range and maximum measurable path loss is, to the best knowledge of the authors, unprecedented in this frequency range.enTHzchannel measurementsTHz transceiverwaveguide module621667conference paper
