The test board kit is designed for convenient measurement of plug-in and SMT devices with NanoVNA or other vector network analyzers. This test board includes a plug-in test circuit compatible with VNWA Testboard, plus additional 0805 and 1206 surface-mount test circuits. The SMT circuit layout does not accommodate all possible test conditions; some devices may require modification. Users should ensure they possess appropriate soldering and assembly skills. The board is shipped unsoldered—soldering tools are required. Users must assemble the test circuit according to their specific testing requirements.
