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.

Dear Joe,
first of all let me thank you for the great work and time you put into
the software. Since a while i use it regularly to measure various kinds of stuff - including using the 2-port feature without issues.

But there is one thing i am missing – as Guido stated below it will be nice to have the possibility to set the Y-scale manually - especially in the window for „Xmsn rectangular“
In example if i want to set upper max to 0 and lower value to -40 giving 5/div it would be nice if this setting will be kept when sweeping anew without automatic scaling.
I checked some step attenuators a couple of days ago – and without auto scaling y-axis it will be more easyer to quickly verify correct switching/attenuation on a wide variety of settings.

Would be an other great improvement in my opinion

Regards

Hi Joe,

My preferences:

- keep it as it is and use the INI file.

- Keep the ability to save and load s1p files.


Would it be possible for the rectangular graph to set the Y-scale manually (min & max)?

Regards

I was asked about the regional settings when using Touchstone files.
Before I make any changes, I would be interested in hearing from those of you living in these areas if you want the Touchstone to reflect your regional settings, always use the decimal, or keep it as is and use the INI file? It's quick change for me, so no big deal but let's make sure that it's the right solution.

Joe, thanks for the new software release. You did a great job.



I tested Rev 2.06 with a NanoVNA V2_2.
In the Xmsn Rectangular diagram, now there is S11 & S22 written instead of Gain & Phase.

Rev 2.08 was tested with a NanoVNA-F.

The latest versions are:
V2 Plus 4:  2.07
Original NanoVNA:  2.09

These correct a few additional problems I found while testing as well as added a couple of features.
