Hello Ulrich
I look s like you load is not 50 ohm. In the calibration you tell the NanoVNA is at center position whatever value it has
Kind regards

Emne: [nanovna-users] Calibration artifact at OPEN #calibration

Hello user group,
I just realized having a problem with calibration OPEN

Going through the device calibration process and everything goes well and I save data at Cal-x

However when I check S0 on SmithChrt it doesn't show OPEN correctly.
The marker should be far right at infinite. However it circles somewhere between 50@ and infinite.

It does not matter if I clibrate directly on the SMA connectors or having a cable in between, effect is the same.
It also doesn't matter whether I leave S0 completely open or having an OPEN-standard connected.

Is something wrong with that device, or does someone know that effect?
