RF demonstration kit is a NanoVNA RF test board independently designed by BH5HNU, with a size of 10 x 10cm Small powerful: 18 functional modules; The board is fully integrated with 18 functional modules. It can be used to measure 30MHz short-wave low-pass filter , 100MHz FM high-pass filter HPF, 433MHz common SAW bandpass filter BPF, 6.5MHz ceramic trap BSF The test parameters of the 18 modes of the test board are shown . Two steps must be performed testing: Step 1. Connect two 20 cm SMA to IPEX adapter cables to the NanoVNA-F machine. : Use 13 short circuits, 14 circuits, 15 loads and 16 path circuits on the test board to recalibrate the machine and save parameters to save 0. The package contains 1 PCB RF test board and 2 20cm adapter cables. Material: pcb colour: green Package Contents: 1 x network analyzer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
