The Testboard kit allows VNWA users to assemble a useful Component jig to quickly assemble a simple RF circuit and evaluate their performance on the VNWA.
This is useful for Experimenters, Students and seasoned RF professionals alike.
The kit comes complete with parts to assemble your own Short Open and Load plug-in (SOL) calibration parts.
For more information download Tom Baier’s Slide Presentation which shows how to use freely obtainable RF Modeling tools to design simple circuits and then evaluate their performance on the VNWA using the Testboard.
Cost- effective tool for obtaining repeatable VNWA and optimum operational performance
Experimentation with this Testboard Kit is featured in Chapter 24 of Gerfried Palme's book 'Measurements with the DG8SAQ VNWA 2/3 Vector Network Analyzer'
English Language Version available from our Webshop
German Language Version 'Messen Mit dem Vektor-Netzverk Analysator VNWA 2/3' available from Funkamateur
