 Calibrate the spectrum analyser after setting a 100MHz span centered ad 100MHz (10MHz/div - 5dB/

div).

 Connect the input of the filter to port 1 of the network analyser, connect the output of the filter to a dummy

load.

 Display the reflection coefficient (parameter s11). The calibration consists in acting on the coils (L8, L9,

L10, L11) to obtain a curve as the one shown in picture A after closing the module.
