?I think I have one of the original NanoVNA's because I can't do the TDR option with mine and I have tried to do firmware updates to it and that feature still won't appear. Is it just selected few models of the NanoVNA that do the TDR option or can all of them do it? I am just wondering before I go and buy another one so that I have that feature. I have no idea what version I have because everytime I turn it on the screen goes so fast I can't see what the version is.

A correction David. The latest "F" has up to 301 calibration points.
Version 3.1.

The question regarding functionality and applicability has not been
addressed, so.......:

For the 'most' part, advances through the evolution of all the NANOs has
been a larger screen (I first bought the small screen and had to use a
magnifying glass for my 74 year old eyes), increases in (S+N) / N,
especially at the high frequencies, and increases in the highest usable
frequency of the units (I believe the latest now stops at 4 GHz?). I

have

pretty much stopped at the NANO SAA-2N (which I still am unable to

connect

to a PC). My NANO-F is the workhorse (outside of the HP 8753C which is

NOT

portable!!), especially at the antenna feedpoints.

The NANO-F is a good choice for you as you can turn off the other three
displays and use only SWR (personally, I prefer the Smith Chart). Just

be

aware that as a stand-alone, you have only 101 points of cal. and
measurement across your entire set frequency range. Connected to a PC

or

laptop, you have as many as 1010 points of cal. and measurement using

Saver

or other dedicated apps.

Okay. Here's my story: I recently returned a Nano H (the one with 4.0"
screen) because although I bought a new one, the one sent was obviously
used. In it's place I am awaiting delivery of a Nano-F (4.3"/metal box,
etc).
My question is (and my mind is totally "fried" from reading bits and
pieces about Nanos in general) did I make a mistake. I want the device

for

general antenna work. SWR, etc. I don't even expect to worry about

using

through devices. I am concerned, and more than a little bit confused,

as

to

what to expect. I am not into lab type experimentation, I don't even

want

to attempt firmware upgrades (BTW, do I really have to?). I just want
something to support "looking" at my ham antennas, tuning, etc. If a

"F"

is

ordered, what does one get operationally? Is a nano a nano, a nano?

Again,

I'm not a rocket scientist (although reasonably technical especially

with

RF) and this purchase/research thing has been one of the most confusing
I've ever been involved with!
Am I in the ballpark or did I make another mistake that I'll have to
return? Thanks for insights!

I found nanovna server doesn't work on windows 10. It may be the same for
nanovna partner...

Can I use NanoVnaPartner on a Windows10 (64bits) machine or is it only

Well, he asked for Gerber files. I have not found an inexpensive program
that will produce Gerber files yet. ExpressPCB used to have a free program
that would convert your ExpressPCB design to a Gerber file but they removed
the program from their website and I never downloaded it. They WILL produce
a Gerber file for you IF you have them make some boards first.

Indeed, you cannot draw a pcb layout with Ansoft Designer, but the

The program itself can be downloaded (DesignerSV050610, version 2010) from

The tutorial page provides a link to download the tutorial in a similar
way.
