I keep making incremental progress on this methodology, Michael, but progress nonetheless. Using

Hi, this is bug introduced in V2.5.2 of VNA Tools. There is workaround for it, see see https://groups

Hi, LRRM_Opt_01.calcfg needs QSOLT_01 as start values for the optimization. LRRM_Opt_01.calcfg is

Good news, Michael. I was able to save the impedance states as databased standards and refer to them

This could be due an unhandled exception when VNA Tools loads the user.config file: Unhandled

Hi, The fix works. Thanks for the suppport. Regards Claes RISE, Research Institutes of Sweden tisdag

Hi, this is not possible at the moment with a GSOLT calibration. This is a limitation of VNA Tools.

The Linearity tables are empty for your defined VNA. See Database / VNA Device / Linearity. See an
