Re: NanoVNA-Saver 0.1.1


 

Hi Rune,
first impression is outstanding!
If you take a look at the BP-Filter I can't find the value of the width for the bandpass in respect to the -3dB points. Same for the -6dB BW.
LP&HP analysis looks good.
For the narrow band SFZ450F BP-Filter we have two problems: If you go higher than 1 segment you can't set a marker (same problem I already reported).
If you select 1 segment, you can set a marker, but due to the fact that the filter is not matched to 50 ohm the analysis doesn't find the correct BW because only one peak is analyzed.
General remark: In order to find the -3dB points correctly the calibration needs many points. Depending upon the filter type you might need more than 20 segments.

Rune, this a large step ahead! Very well done!
Thank you very much for all the work you have done!

Kind regards
Norbert, DG1KPN
