Abstract
En 中文
We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art WM-380 (WR 1.5) rectangular-waveguide vector-network-analyzer measurements over the frequency range 500-750 GHz. We use the analysis to assess thru-reflect-line, thru-short-match, and thru-short-radiating-open calibrations. The comparison shows that thru-short-match and thru-short-radiating-open calibrations outperform thru-reflect-line calibrations, and that this is true even when multiple lines and optimal averaging are used to improve the thru-reflect-line calibrations.
