Hi Ady.
I only did a screen capture. The measurement and cal are one port only. So I would have only S11 data available.
The main thrust of the post is you need to capture a reasonable number of data points, 10 bands for 100 kHz to 30 MHz was used. You can probably get by with much less. Perhaps 401. The series loops appear with no added short applied. The choke is measured in place on the chassis. Take care with this placement if you are concerned about a problematic loop near an operating band!
A one port measurement appears sufficient.
I can capture a S data file. Might be of interest if you desire some other form of display or post processing. Although this is all very nice, I am not parting with my GDO!
