The German Powerpoint presentation created by DG8SAQ is translated to English, Danish and Japanese, also available as pdf files: Furthermore a written Transcript in English of the original presentation is also available as pdf file, for a detailed study of the presentation. This Transcript used for creating the English soundtrack, and may be translated to other languages. Fell free to do so and let me host it here.
Also translated into Japanese Language is my guide for calibration, using the Amphenol Connex Cal standards, available from SDR-Kits and ICAS Enterprises. The document name is Amphenol Connex Cal Standarda rev3-jpn.pdf and represents the lastest changes and improvevements to the calibration settings. From VNWA version 36.2.xm onwards the calibration settings includes a Thru Adapter modeling, removing the delay of the Thru Adaptor during S21/S12 calibration. The Amphenol Connex (SOLT) Calibration kit exist, in both Male and Female versions, and can be purchased from SDR-Kits and ICAS Enterprises at fair prices. In the document you will find all the relevant data for setting up the VNWA software, for a quality calibration, provided the data described is used.
