背面印刷了史密斯圆图，可以用于学习识读史密斯圆图，学习阻抗匹配基本原理。
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.
测试板18种图案测试参数说明如下，测试前必须两步操作：
1、将附带的两根 20CM SMA转IPEX 转接线连到 NanoVNA-F 机器。
2、使用测试板上的13短路、14开路、15负载、16直通电路重新校准机器，并将参数存入0。
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.
