3.4.8
For the alignment procedure of the tuner module two programmable switches are
integrated to bypass the bandpass, the SAW driver and the SAW filter. The first switch
called “IF switch” can switch between the mixer output signal and the bandpass output
signal. The second switch called “Loop thru” can switch between the signal after the first
stage of the IF AGC amplifier and the SAW filter output signal.
