OK, but not knowing what that is, did anyone rewrite the manual in English? The words are all english but don't make a whole lot of sense. Reminds me of the days when the off shore boys wrote the operational manuals for ham radios, UGLY.
Some background might help.
You didn't buy a commercial product with an R&D division, marketing,
and support departments.
You bought one man's hobby project; one that he open sourced.
The Chinese industrial system found it and began producing them -
that's how we ended up with one.
The originator, Tomohiro, has a Github where he released the firmware;
the software that runs on the device itself. Also in that package are
Python programs that allow one to interact with the device from a PC,
Mac, *nix, etc. His 'handle' is 'edy555'. Tomohiro is Japanese;
English is not his first language. A Chinese programmer has been
modifying and enhancing the edy555 firmware; that is 'hugen'. Hugen's
first language is not English. Hugen has released a PC application
that is more polished than the original Python scripts. There are
other PC-side developers as well as people working on the firmware.
We are reaping the benefits of early access to the physical device and
to the firmware that runs on it, and to the software being developed
for the PC. The downside, if one can call it that, is that virtually
all of the work is being done by people for whom English is not their
primary language. In addition, the software changes are very frequent:
people on the list are almost certainly discussing software that
didn't come on your particular device from the factory.
There are two areas in this group that might prove useful for
self-education. The Files section, and the Wiki. Since this is
actually quite early in the life of the NanoVNA, neither resource is
all-encompassing. But several people have been continuously improving
them as time allows. In particular, the Wiki is a resource that any
one of us can edit/enhance - anyone can contribute a note or a brief
writeup that would help the next newcomer...
OK here is where I am. I have a rudimentary knowledge of the NanoVNA and have walked through a lot of the set up. NO where in the manual does it tell you step by step how to get rid of the Smith chart overlay.
The Smith Chart is tied to one of the traces. Turn them all off. On
the NanoVNA, select Trace, then de-select all of the traces. Voila, no
Smith Chart.
Now, turn one trace on at a time. The description of the current
assignment appears in the upper left.
If you'd like to re-assign a visual graph to a specific trace, choose
one of the traces. Note that there are two traces for CH0 and two for
CH1.
Select the trace you'd like to re-assign.
Press Back. You should see the menu with Trace, Format, Scale,
Channel, Transform'.
Press Format. You should see the menu with the various graph types,
'LOGMAG, PHASE, DELAY...'
Press the format you prefer.
You've now assigned your choice of graph to the trace.
Next, nothing on interface to the computer NADA. Nor does it tell you how to download new revisions.
Much of that is in the Wiki and Files section. As I said, we're still
in the early days, so help organising things is welcome. The thumbnail
is that there are several PC-side programs. Look for NanoVNA-Saver.
I'm old fashioned, so I prefer to go direct to the author:
Welcome to the community! I hope some of this was of use.
