Really good for testing my VNA and for better understanding how my VNA works.

Excellent module that I use for calibrating and demonstrating my NanoVNA Antenna Analyser. It comes with 18 built-in circuits which are connected using the supplied two UFL male patch cords.I found these patch cords initially fiddly to use. They need to be firmly lined up and pushed on. Care is also required on removal. I recommend easing off with a flat screwdriver. Spare patch cords can easily be sourced on Amazon.It would have been nice to include some documentation but it is more or less self-explanatory.Overall a nice module which does as described.

This demonstration board is well designed for demonstration of alternating current to beginners. It starts simply with the most basic frequency band pass filter to the best known smiths charts which nearly every rf engineer uses. However the performance may not be good enough for uhf testing.
