What It Is

Hermes, an SDR RX/TX board designed by the HPSDR team, has many different uses. In particular, with the addtion of a simple reflection bridge, it becomes a Vector Network Analyzer, a powerful tool for analyzing the antenna systems and radio circuits. The board comes with Hermes VNA software that implements the basic functions of data collection and display. HamVNA presented on this page is an alternative to that program that provides more functionality and a nice, easy to use interface.

HamVNA can display and analyze the data from two sources:

• collected using the Hermes hardware;
• collected on another VNA hardware and saved in the TouchStone format (*.s1p and *.s2p).
