The RF Demo Kit is a NanoVNA RF test board independently designed by BH5HNU, with a size of 10 * 10CM. It is used to learn the use of a vector network analyzer.
You can get one on AliExpress Deepelec Store and we support shipping to most parts of the world.
The Smith chart is printed on the back, which can be used to learn to read the Smith chart and learn the basic principles of impedance matching.
The test parameters of the 18 patterns of the test board are described as follows.
Two steps must be performed before testing:
Step 1. Connect the two 20CM SMA to IPEX adapter cables to the NanoVNA-F machine.
Step 2. Recalibrate the machine using the 13 Short, 14 Open, 15 Load, and 16 Thru circuits on the test board, and save the parameters to SAVE 0.
