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

John,? Very interesting and stuff.?? Thanks,Mike WY6K "... somewhere in the distance, there's a tower and a light, broadcastin' the resistance, through the rain and through the night..."

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..

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

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

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

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

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

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

Interesting: Does the use of the ADF4350 mean the minimum frequency will be 137MHz+? Or do you have plans for handling that? Are you and your project associated to edy555/ttrftech, to hugen, or to

Forgot to mention...the 85050B’s calculation were for 1500 MHz (corrected this -- I'd originally typed 900 MHz) - Jeff

This post is somewhat off topic but I am so happy with what I achieved I felt I earned some bragging rights For those that need a nanoVNA V2 for tuning their 2GHz antennas there is no real reason to

Steve, That's good information. Some Linux user's with bricked devices may not have been aware that a Windows PC might be able to recognize the device (if they still had a Windows PC available) and

reply to kb3cs That's certainly annoying. I'd like to have a reference for where these regulations abide. Do you have it handy? thanx W5VZB

I finally got mine unbricked using "conventional" methods. Here's the story: 1) Used ubuntu dfu-tool to load CLEAR_MEMORY_DFU.dfu . That left the NanoVNA white screened. 2) Tried to use dfu-tool to

Steve, The following is what another user wrote: // Begin Quote // There are two ways to update firmware: DFU and ST-LINK. So, it depends on what method you're want to use. 1) DFU update. This is

It's alive ! For anyone patient enough to be following this, here's what happened and what fixed it: 1) Used ubuntu dfu-tool to load CLEAR_MEMORY_DFU.dfu . That left the NanoVNA white screened. 2)
