Measuring impedance of the rectifier

I built a rectifier circuit for WPT project.  This rectifier is used at receiver to convert AC from the coil to DC. Here are the pictures and the circuit diagram. Please look at the R1 in left side. The R1 is need to match the impedance of the system. The value should be 50 Ohm, But I use 47 Ohm instead here because of the simplicity of the circuit.  The rectifier is using the full bridge diodes and the LED is terminated to R_load serially. First, We need to setup the measurement program of the VNWA. At the display setting (keyboard “d”) : Let the traces are enable, Trace 1,2,3,4,6 […]
