Still new to using a VNA.
I've calibrated my NanoVNA-H4 and double checked the calibration with the 3 tips once again as per hexandflex' guide, with the isolation and through, since I want to measure the coax loss.
So far so good.
Now when I plug in the cable to both S11 and S21, I get some really odd readings that don't seem to match up with what I'm seeing in guides and videos. My logmag is all over the place and nowhere near showing a proper reading.
What is it that I'm missing here? Did I do something wrong?
