Re: The T-Check confusion
Hi Gabriel You are right it is a matter og software and for that matter firmware. As the NanoVNA is presently it does not have facilities embedded for neither calibration kit data and full 10/12 term

Re: The T-Check confusion
I've deliberately chosen not to rely on scikit-rf in NanoVNA-Saver. Library reliance is kept at a minimum, and figuring out the mathematics behind the calibration was part of the fun of writing the

Re: The T-Check confusion
Kurt, It appears (in my limited understanding) the poor matching to Z0 of CH1 (port 2) is the biggest reason why the T-check is not performing well on the nanoVNA. Would you agree that using a 10dB

Re: The T-Check confusion
Hi Herman First of all it is not the mini-VNA it is the DG8SAQ VNWA. Sorry these kind of measurements is only possible with a VNA having 10/12 term error correction facilities. NanoVNA is not able to

Re: 1.5 GHz ??
No configuring necessary.? Simply key in the frequency. By default it comes up with 900 MHz but you can ask for up to 1.5 GHz and you will get it. Bob
