Re: Simple way to produce calibration standards #calibration
Only non-inductive resistors are needed around the GHz, which must be soldered to the connector and cut off excess feet. The calibration on the images is appropriate for the shortwave. Calibrations

Re: NanoVNASaver -- save points?
The nanoVNA-Saver does not automatically load previously saved data, but you can create a lot of calibration data yourself and download it as a calibration data before use. You can comment on the

Hello, I thougt abiut that too for a while. IT would be ideal if SaverSw would be extended such that it could recall all four Cal Data in the nanaovna decice. I am using different fixtures, all

Hey dr ops. When I calibrate NanoVNA with NanoVNASaver and save the data, will it be loaded automaticaly if I start NanoVNASaver again? And: Is there a transfer between NanoVNASaver and NanoVNA save

Re: Simple way to produce calibration standards #calibration
The BNC calibration standards are not nearly as good as the SMA ones. There is more stray capacitance and series inductance in BNC because of the bigger size. I made BNC calibration standards and they

Re: Simple way to produce calibration standards #calibration
Why not use ordinary BNC hardware with an adapter?? Maybe not good all the way to 900 MHz but fine for casual use. Bob

Sign of format LINEAR in the NanoVNA
I am using Hugen's latest AA FW but have also checked with QRP's latest. I am under the impression that the format LINEAR is equal to rho, the absolute value (modulus) of gamma (S11), and that the
