Version 3.1.18 of vna/J is released.

  • The application JAR can be downloaded from here as usual.
  • There s only one small change in 3.1.18 - |Z| is calculated correctly when using port extension

There were some user reports, that miniVNApro with firmware <2.6 is only working with vna/J < 3.1.15.

This is due to a miniVNApro firmware bug for versions <2.6.

  • miniVNApro with firmware < 2.6 is only working with vna/J up to version 3.1.14
  • miniVNApro with firmware = 2.6 is working with all versions of vna/J

Firmware 2.6 is mandatory using the extender and/or vna/J > 3.1.14.

To use all version of vna/J > 3.1.14, you have to update the firmware of your miniVNApro to the newest firmware.

It's up to you ...
