With a 1x4 FCM configured node, all four output ports can be tuned by
injecting the signal into the Rx1 connector. Only the 2 lower HPFT Modules
are adjusted for this mode.

With a 2x4 FCM configured node, ports 4 and 5/6 are tuned while
injecting signal into the Rx1 connector. Ports 1 and 2/3 are tuned while
injecting signal into the Rx3 connector.
injecting signal into the Rx1 connector. Ports 1 and 2/3 are tuned while
injecting signal into the Rx3 connector.
With a 4x4 FCM configured node, ports 5/6 are adjusted using the lower
right HPFT module with signal injected at Rx1 connector, port 4 is
adjusted using the upper right HPFT module while injecting signal into
Rx2 connector, port 1 is adjusted using the upper left HPFT module with
signal injected at Rx3 connector, ports 2/3 are adjusted using the Lower
left HPFT module with signal injected at Rx4 connector.

For the upper HPFT modules, only higher modes of segmentation needs
HPFT modules adjustment.
As shown in the picture above, adjustment 1 is used to fill any dip in the
forward band; adjustment 2 is used to optimize the response at the highest
frequency in the forward band; adjustment 3 is used to optimize the
response at the crossover to the forward band.
