Verification of the channel filter  connect a network analyser to the channel filter and calibrate its
components to obtain the desired frequency response:
q Configure the module with PwrCtrlMode Man and verify that it is possible to change the gain of the filter
by acting on PwrLevelMan, setting JP1 Remote.
Verification of the wide-band amplifier section  connect a spectrum analyser with tracking between J4
and J5 check that the frequency response of the amplifier is flat within 1dB from 50MHz to 900MHz.
