Re: NanoVNA V2
Hello If I was to measure a 23 cm antenna, let alone one for 13 cm or 9 cm, I would NEVER EVER place an object the size of the NanoVAN at or close to the antenna. Thus size is not important. In a

Re: NanoVNA bricked
I had great difficulty flashing in DFU mode. At one point I thought the VNA was bricked. For whatever reasons, I was unable get DFU running under Linux. Under Windows, it finally worked but took

Re: Cal-Kit Standards' Definitions
Hi Jeff I have given a report I made on the last day of 2017 a brush-up which you can download from http://www.hamcom.dk/VNWA/How to design a homemade male BNC calibration kit.pdf It is a full blown

Re: nanovna Battery Specifications
Dr. Dave I already noted that you cannot see the -60 dB point on a filter in through mode with a dynamic range of 40 dB. And I already noted that 99% of the time I personally do not need to see the 60

Re: NanoVNA V2
In my opinion, it could be a bit larger with a larger screen and still be fine for portable or field use.? Just look at the Keysight Field Fox... Mike WY6K "... somewhere in the distance, there's a

Re: Si5351A max fundamental frequency
It's somewhat different, does not really matter Till 300MHz both test signal and 5kHz offset LO are fundamentals. From 300 to 900MHz test signal is 3rd harmonics so actually from 100 to 300MHz and the

Re: NanoVNA-Saver 0.0.12
More ideas. If possible query the firmware name and version. When, if, possible set the max fundamental frequency. Possibility to load Elsie data. The problem right now is that Elsie doesn't export

Re: NanoVNA V2
Hi Personally I am not at all sensitive to the form factor. My use is 99% lab use and 1% antenna/portable use. I wonder how many actually wants a small form factor. Bo

Re: nanovna Battery Specifications
Warren, Dynamic range of a VNA is a parameter of importance in *transmission* measurements, if for example you are looking at the attenuation of a filter. My HP 8720D has a measured dynamic range of

Re: Si5351A max fundamental frequency
My understanding is that flashing Nano**800_aa*.dfu ("aa" instead of "ch") is needed for changing max frequency. Then load "ch" version for that functionality..

Re: More comparisons of NanoVNA and Keysight analyzer
Hi one suggestion , why not export the traces on s2p format and plot the traceto be compared , using the Avago program APPCAD ? Best Regards IZ1MDJ Maurizio

Re: Cal-Kit Standards' Definitions
I don¡¯t know if you have an 85032F, but if you do, you will find the male and female opens have the same coefficients in your 8753D. But Agilent later revised the coefficients, with different ones

Re: Si5351A max fundamental frequency
Hi I have now upgraded my NanoVAN with the NanoVNA-H__800_ch_20190924.dfu firmware. However, as the attached picture show there is not much real change except that the abnormality has moved down in

Re: NanoVNA-Saver 0.0.12
Thanks uni berry, that was exactly the problem. The Kaspersky "File Anti Virus" button has to be turned off for NanoVNA-Saver to launch which it does after that. Before I ran NanoVNA-Server, I scanned

More comparisons of NanoVNA and Keysight analyzer
I used a few LP filters and a mobile V/UHF antenna to test the NanoVNA against a $$$ analyzer: https://ae5x.blogspot.com/2019/09/more-comparisons-with-nanovna-and.html

Re: NanoVNA V2
Gabriel, Hugen posted last night that a 3.5" display could still be part of the final design. The NanoVNA has been really well received but one of the most requested feature updates has been a larger
