Toshiyuki (JP1PZE) has again provided another translation for vna/J.

Please find the "Driver guide for the miniVNApro" translated to Japanese for download in the manual section!

The new version 3.1.4 of vna/J is released.

As a new feature it supports now overscan in calibration mode 1. Please check chapter "User defined" on page 98 of the user guide.

The application JAR can be downloaded from here as usual.

Here is a collection of measurements I've done with vna/J.

Since version 2.9 of vna/J a command-line version of the vna/J GUI is available (I call this version also headless).

This command-line version can be used to execute automated scans, when no GUI is needed or graph-ical screen output is available.

Details can be found in the user guide for the headless application.

I'm experiencing problems with the serial library on Mac OS X machines - the XON/XOFF protocoll, which is required by the new bootloader, is not working as expected.

I'm doing some research on this problem ... But you can use the latest version 3 JAR also on Mac OS X except the firmware load function for the miniVNA tiny analyser!

If you want to update the firmware on the miniVNA tiny please use a Microsoft Windows (XP, VISTA, 7, 8, 8.1) based PC.

if you get a message from the OS X, that this developer is not valid, try to switch the App-Download permissions on the security tab in the system settings to "Mac App store and verified developers".


The new version 3 of vna/J is available for download. This is the first version which also supports the new miniVNA tiny. It can be downloaded as usual from here

A driver guide for the miniVNA tiny is not available, but will be provided in the near future.

Due to lack of time, the current version is only tested on Windows - Mac OS X is currently under testing.

Ich habe am 16. Mai 2013 anlässlich eines OV-Abends des DARC Ortsverbands Sindelfingen (P42) einen Vortrag über die Analyser von miniRadioSolutions und vna/J gehalten.

Die Folien gibt es hier als Download. Danke auch an die Teilnehmer für die freundliche Aufnahme und die rege Beteiligung am Vortrag - hat Spass gemacht!

PS: Hans-Werner - Dein Notebook war die Rettung ;-)



  • Ich habe 2013 einen Vortrag im DARV Ortsverband P42 zum Thema vna/J und die Analyser von mRS gehalten. Hier gibt es weitere Infos.







Ich habe ein kurzes Video erstellt, in welchem die eingebaute Firmware-Updatefunktion in vna/J gezeigt wird. Es zeigt die im Treiberhandbuch beschriebene Vorgehensweise. Sie können es sich hier anschauen.


I've created a short video how-to use the integrated firmware update function in vna/J. It shows the firmware upgrade as described in the driver guide. View it here.

Beim Aufräumen meines Shacks bin ich auf einen älteren 2m-Vorverstärker von Burdewick gestoßen. Dem bin ich mal mit dem miniVNApro und vna/J zu Leibe gerückt.

Ein befreundeter Funkamateur hat mir ein UHF-Filter vom Typ FUBA RZK715 ausgeliehen

Dieses habe mit dem neuen Externder für den miniVNApro durchgemessen.

miniRS hat das Gerät jetzt auch offiziell mit Daten angekündigt.

  • Frequency range 200-1500 MHz
  • Dynamic range : 60 dB @ 1 Ghz
  • Operation mode : Reflection and transmission S11-S21
  • Harmonics: –35dbc
  • Directional coupler : internal
  • Calibration : OPEN/LOAD/SHORT
  • Connector type : SMA
  • Output Power –10 dbm (aprox.)
  • Power consumption : 150 mA

Hier nun meine ersten Eindrücke.

"Timeout" or "Check communication port" problems with newer versions of vna/J - check this post.
