Re: Download NanaoVNA Labview
My company has the full $3,000 version of LabView. However, there's a VERY INEXPENSIVE version available for "Home" use at $49 from Digilent: It is the 2014 version - but for most hobbyists it's all you need.

It is Labview a National Instruments product and its pretty nice tool for
building test or measurement systems and even simulations. I've used it
with PNAs to build step and repeat measurement systems for antennas
ranges.

That LabVIEW application was written by a gentleman over at eevblog and he is not releasing it to anyone. It runs on LabVIEW.?

Hello PJH,
thank you for asking about my involvement. My involvement is "only"
software, yes. ;-) I have had some pokes at the firmware, but nothing
published - it was these attempts (at increasing the number of data points)
that led me to develop NanoVNA-Saver in order to solve that problem. It was
further prompted by the lack of any open source and community-supported
software for the NanoVNA. By now there is a number of software options -
but as far as I can tell, still only one that's licensed as "free software".

Who is edy555? Who is Hugen and how is he involved? What is the involvement

Re: Download NanaoVNA Labview
It appears the software is National Labview- prepare to take out a mortgage.

Re: Download NanaoVNA Labview
I believe LabView is a product of National Instruments. I hope I'm wrong in this case, but anything from National Instruments costs lost of green backs ($$$). Dave - W?LEV On Tue, Dec 10, 2019 at 9:18 PM Hans , PA3HGT via Groups.Io <pa3hgt= [email protected]> wrote: Hello all,

Re: Using the Nano as a receiver?
Thanks for your comments! Based on these I was able to verify this functionality. There are two issues:
the bandwidth of a typical FM signal
the low sensitivity if the Ch1 input
With only 101 points on the display you have to look quite thoroughly for a 100kHz wide signal in a 50kHz ¡ª 900MHz scan. It is physically impossible to see. Only when I use 5MHz scan steps you can clearly see the signal. With only ?VHF¡° given as frequency indication that required a lot of runs from 100 to 350MHz. I did find the signal from that wireless microphone at 251.6MHz.
In addition you had to hold that micro quite close to the antenna to make the nano register the signal. Supposedly it transmits with some 10mW which should be plenty of signal in a distance of 1 cm from the receiving antenna.
Regards

Patrick, Please browse the forum Wiki /g/nanovna-users/wiki/homeedy555 is a Ham located in Japan and essentially took an existing idea from a couple of Texas Hams and developed sophisticated software and created a kit for the original NanoVNA and opensourced all of it. /g/nanovna-users/topic/51382131#6796Look at the files section on the forum where I've placed his original (translated) design notes: /g/nanovna-users/files/Miscellaneous/NanoVNA%20design%20notes%20by%20edy555Gen Hu (hugen), a Ham in China then took edy555's design and improved on the software and hardware and began selling them as assembled devices on the TaoBao website. Soon, a pile of copies/clones appeared of hugen's design.Now, version 1 of the NanoVNA hardware which tops out at 1.5GHz is mature and edy555 & hugen are working with others to design NanoVNA V2 that will go up to 3GHz. In the meantime, another developer created the NanoVNA-F with a larger screen but tops out at 1.2GHz You really need to go through (all 8000) forum posts as everything you need is there.?

Re: CAL -> RESET -> CALIBRATION clarification...
Herb and Larry thanx both,
all clear now, confirming what I thought and hoped that CAL->RESET doesn't clear the current contents of C0-C4 while "clearconfig 1234" does.
Best regards and thanx again for the great work that you and many others are so generously giving to the rest of us... I hope one day to be able to contribute too.

Re: THE NANOVNA - A COMMENT
Great comments!? I add my "Whale Done" to them.
I haven't begun to fathom the depths of the Nano, but I thank those who poured themselves into the design and manufacturing of it.
I have had and used the HP 8753 for years and now have 3 small VNAs including the Nano.? They are all helpful.
Keep up the good work,? It is appreciated.

philosophy in such things is that a milligram (choose your unit of measure)
of positive praise goes an astronomical units (again, choose your unit of
measure) farther than 1000 kg of negative dressing down (a.k.a.,
criticism). So, with that stated:
Thank you ALL who brought the AFFORDABLE and highly FUNCTIONAL NANOVNA to
the market!!!!! It is a wonderful tool for the amateur and certainly,
based on the emails I read, a motivating tool for learning many of the
finer points of RF design and more than just basic SWR. Guys and gals,
well done ! ! ! ! ! What an instrument for all of US $50. Again, well
done........ And all this should include the "saver" SW.
I own an HP 8753C with the HP 85047 S-Parameter test set with a bunch of
additional RF and low microwave test gear, mostly HP. I know how to use
these instruments. But comparing the NANOVNA to the HP 'equivalent' which,
in its day, cost 1000X the NANOVNA , you did a bang-up job. Please
continue the efforts and offerings. It IS appreciated. And, BTW, the
noise floor using s11 with my unit is about 10 dB better that advertised.
Again, thank you for offering an affordable, motivational, capable, and
educational tool to the average amateur (and a few EE's who can't even do
Ohm's law....).

PS: I have a pair of 'senior' eyes at 73 years of age (wisdom) and do wish

Re: errors of "error" models
I'm still trying to understand what you are publishing. Am I correct your model as published in the white on black picture is a one port model like this and you describe how to determine the model using 3 known DUT's as in this Where you still have to solve the three equations but as I am laizy I use Maxima leading to this result: Or am I completely failing to grasp what you are trying to convey? -- NanoVNA Wiki: /g/nanovna-users/wiki/homeNanoVNA Files: /g/nanovna-users/filesErik, PD0EK

There is no advantage. The 101 points are across the frequency range displayed.
===========================================================================
The advantage comes in how the 101 points are used.
If your original configuration was for 50k -900M, then the 101 measurement points are about 8.9 MHz apart. The stored calibration points are also 8.9 MHz apart. In the 50K- 30M you only have about 4 measurement and calibration points available.
If you change your configuration to 50K-30M, then the 101 measurement points are now about 297 kHz apart. You have better frequency resolution, however; you still have only 4 calibration points available and a lot of interpolation will be involved. This can result in quite inaccurate VSWR readings and demonstrates why it is important to re-calibrate when you change your frequency range.

hi all,ive an old hp limiter from an old spectrum analyzer. Its a 5086-7282 0-1.8ghz, is it worth putting this on the input port of my nanovna as a protection,is it a goog idea or bad?,73.
=============================================
The 5086-7282 is a diode limiter. Diodes are non-linear devices and can introduce uncertainties in your measurements. The input port of the NanoVNA is CH1 and placing the limiter there would protect the port from signals greater than 30 dBm (if I remember the specs for the limiter correctly). I believe 30 dBm might be higher than the NanoVNA is rated for and would give you a false sense of security.
I can't recall any commercial or amateur VNA designs with a limiter on the output port (NanoVNA CH0) because of the non-linearity issue previously cited.

Read up on the various messages that talk about the reference plane.
The limiter will limit when it is connected to the Nanovna but if you are performing antenna testing, if the Nano is floating, it becomes part of the antenna system and readings can be incorrect.
