Re: edy555 NanoVNA-V2 Screenshot #edy555_nanovna
hugen, Thanks for the additional information. Do you know what generator chip is used for 700 MHz fundamental operation? I agree the noise is higher than I expected for a second generation design, but

Re: edy555 NanoVNA-V2 Screenshot #edy555_nanovna
4.2 GHz is uint32 limit Vs 700 MHz harmonic frequiency should be 700Mhz 700 - 2100MHz 2100 - 3500MHz 3500 - 4900MHz ....

Re: edy555 NanoVNA-V2 Screenshot #edy555_nanovna
The edy555 NanoVNA2 still uses a 2.8" display, with harmonics above 700MHz. Use ADC arrays to speed up scanning. At the moment it seems that the noise is still relatively high and the manufacturing

edy555 released a screenshot that appears to be his prototype NanoVNA-2 operating to 4.2 GHz (see attachment). No other details were provided. The s21 noise floor in the attached photo indicates that

I've put the PHSNA User's Guide in a shared folder (see link). I think the groups.io group still accepts members. The moderator is N5IB. The User's Guide wouldn't be of much interest to most nanoVNA

Hi, First - I am new to the nanoVNA and working a little every day to climb the curve. Antique antenna myths and an SWR bridge have defied me for several years since I moved to this location - even

Re: Pro or Con
Of one knows the nanoVNA, one knows that it can simply trace SWR/Impedance, and nothing else. Just a line. For less than 50USD, its not possible to find a more accurate device, even for "antenna

The MFJ analyzers and the NanoVNA are two different animals. If what you want is measuring SWR, and nothing else, the analyzer is for you. If you ever worked with a VNA, and know the repertoire, you
