NanoVNA V2.2 does not work Cal shows scribbled graph all over

Hi All,

My NanoVNA 2.2 does not want to calibrate... Once done it shows graphs all over the show...

Please advise?

Check your calibration kit, or NanoVNA conectors/cables

In most cases you have broken 50 Om Load, check it

Hi There,

Thank you, already borrowed a friends calibration kit... No success... Its a brand new unit... I've order another one from another supplier and sent requested a return to supplier....

"scribbled graph all over"

I've had this happen on several of my nano's, make sure to perform a reset.

Hi There,

Thank you, I've done a reset even firmware upgrade...

S O L cal reads same wrong value... Even using friend calibration set... This cal set works fine on his NanoVNA....

Frustrating... Feels like I bought an expensive brick....

Jaco
