Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

nanoVNA -saver - no VSWR display #nanovna-saver

Anne Ranch 2022/06/07 08:13

I can do "analyze" and get "minimum SWR", but have no VSWR display (graph) at all.
bug or am I missing some setup ?

The device display has to have "SCALE" set to be able to see SWR display,
nanaoVNA_saver has no such setting and the vertical scale is fixed , cannot be changed as far as I can tell.
BTW - "return loss" graph works as expected.

Hello Anne!
Haven't you tried using another program, NanoVNA APP, for example?
Download here NanoVNA-APP-1.1.209

You set it as S11 VSWR and with right mouse you can set scales to your hart content....

Set at 'display setup'     S11 VSWR.
with right mouse you get the 'scales'...

Hi Anne,

This is a Google pop up to tell you how to manipulate files on Google Drive.  (It is informative only.)

Just hit the X in upper right to close the pop up and you should see the referenced program(s) for download.
