Re: New open source VNA released - excellent performance claimed
Indeed - if there were a decent python+libraries on Android, it would be straightforward to move NanoVNA-Saver as a start. If you were *bold* - Java is sort of the native Android language, but I don't

Here's a nice article on measuring components with a VNA, discussing the three test configurations - fixturing, error analysis, etc.

Connect Antenna Trap to NanoVNA
Hello all... I'm new to VNA's, and need some guidance. What is the way to connect my NanoVNA-H to a dipole antenna trap so I can tune it, and read resonant frequency, Q, impedance, etc.? Thank you for

Re: Current Firmware for nanoVNA #firmware
Thank's Klaus. Indeed, when I notice an update, I make changes here as well. -- *** If you are not part of the solution, then you are the problem. ( http://ha3hz.hu/ ) ***

That boom cost includes the milled aluminium enclosure? If so, that is a very good price. If available I would be interested in purchasing an engineering sample, without the case. I suspect that

It is probably a quite limited amount of work to port the PC software to Android. Then simply sell a bundle of a cheap Android tablet (these are cheaper than the screens inside them :-) and the

Calibration issue ?
Hi, new to this group. NanoVna ttrftech v. 0.5.4 NanoVnaSaver v. 0.3.7 I'm trying to use a home made fixture for testing chokes via S21 parameters, two short wires exiting VNA ports ending with clips

Re: Wireless remote control of nanoVNA-H
Yes, connection some. But in my firmware you can select current connection type (USB or Serial), speed in menu in any time. Can configure module from NanoVNA console. Can connect different device and

Re: New open source VNA released - excellent performance claimed
I would venture that the barrier here is not hardware, but gateware/software and ASICs. It's one thing to 'be inspired by' hardware designs, but directly ripping off software/gateware would be a

We have been working closely with Jan and provided all manufacturing support for Jan's second version of the VNA design. The results so far are very satisfactory, but we still need to make some final

Re: Wireless remote control of nanoVNA-H
All of this looks very useful. Cool stuff! Looking forward to seeing how much more detail we get in a TDR display with 401 points. Having the UART available opens up many new possibilities. Thanks!

Re: New open source VNA released - excellent performance claimed
Interesting. As a digital guy, I'm surprised a 6ghz instrument can use an Si5351 as the primary clock source. Rather high jitter, SiLabs has far better. He has two 100mhz channels from the Si5351
