Rohde & Schwarz ZNA network analyzer WR28 waveguide calibration

How to define a WR28 waveguide calibration kit on the Rohde & Schwarz ZNA vector network analyzer, perform a waveguide calibration, and make a measurement with a WR28 waveguide flange calibration plane WR28 frequency range: 26.5 - 40 GHz geometric mean frequency: sqrt(26.5 GHz * 40 GHz) = 32.55 GHz lower cutoff: 21.077 GHz upper cutoff: 42.154 GHz wavelength: 9.214mm 1/4 wavelength: 2.304mm Standards: Short: 0mm Offset short: 2.304mm Match Chapters: 0:00 Introduction 0:08 Set Channel Start and Stop Frequency prior to calibration 0:20 Define WR28 connector type 0:52 Define WR28 calibration kit 2:45 Perform calibration at the waveguide flange interface
