Hello Bryan, I am trying to calculate the T-Check value from the NanoVNA-Saver .S2P file with LibreOffice Calc, but I did not got the T-Check formular adopted. This is already done in the attached

Its in Octave (Matlab equivalent) for now till I know what algorithms to use I have a S11 model for the cable (includes estimating the frequency dependent loss and the Complex static impedance (did

Hi Erik - Do you plan a GitHub repository? What approach for solving model parameters?

Hi Oristo Here is the Screen control for the FA-VA5 I have received from AE5CZ Larry Goga and have permission to distribute as I like Kind regards Kurt -----Oprindelig meddelelse----- Fra:

Hi Oristo The Yahoo VNWA group is in the process to move to a io group which is a better platform for a Wiki which I am sure will come. I have large number of document I will "flood" the Wiki with in

And here is the nanoVNA data with the impedance correction for the long cable ( -0.075 -0.56i ohm) Substantial oscillations are still there and these do NOT come from the calibration kit or the cable

Sadly, I lack the playful approach. Yes, I researched FA-VA5 before nanoVNA, but avoided the software until your prompting because of allergy to controls hidden in graphic user interfaces. That is why

And here is a hint a first order cable correction (assuming the cable impedance is not exactly Z0) can improve the results The model corrects for the long cable impedance mismatch for the 3GHz VNA

Hi Oristo Good to hear about success. It may be a crazy user interface for you being a custom to something else, but not really for me as been the only VNA for me since it's birth. It is for more than

Hi Rune, The new TDR impedance measurement is good too. However it really could use the ability to manually scale the impedance in addition to the length, as the low impedance end of the scale is too

Hi Martin, thanks for the bug report. I'll have a look at it (and probably a fix!) for the next version :-) -- Rune / 5Q5R [email protected]> wrote:

Hi Rune, Thanks for the latest update, especially the ability to change the marker size and the relabeling of the Series L & C values One small bug I've noticed is that the Marker number on the S11

And here are the plots for the 3GHz VNA with the bridge rotated 180 degrees. Still without HW correction model. All differences are coming from a change in bridge HW. -- Erik, PD0EK
