Abstract :
Two competing delay-short calibration standard designs for WM-380/WR-1.5 rectangular waveguide (500-750GHz) are evaluated. Quantitative estimates of the connector uncertainty are made and it is shown that an end-milled design out-performs the shim design. The effect of each standard´s repeatability on calibration uncertainty is used to determine corrected measurement uncertainty for an eighth wavelength verification standard.
