Dear Sirs, buy NANO VNA, I was measuring a passive circuit when suddenly
the point in the three calibration points stopped appearing, that is in CC,
OC and 50 Ohms. Fuzzy graphics appear on the screen, not precise at each
point.
I show some photos showing what happens with the three calibration
points . What
can I do? Thanks a lot. Ing. Daniel Lorenti
