Inter-stage adjustment
The inter-stage adjustment system is fitted with an attenuator and an equaliser system,
controlled using the
JXP
It should be noted that the inter stage pre-equalisation enables the achievement of higher
output levels for fmax using the same intermodulation parameters.
The selection of the appropriate inter stage attenuator enables a lowering of the output
signal level without degradation of the signal to noise ratio.

Output amplifier
It is possible to divide the signal inside the amplifier using STI, or
notice that in the case of a non-symmetrical division, the tapped signal will be applied onto
OUT1. If you don't wish to use this functionality, use a
6. Return path
The forward and return path signals are separated from each other on the diplex filters
(DPF), fixed on the amplifier's board. The return path signal is then applied onto an ingress filter
that may be connected or disconnected using a jumper. Selection between the active or passive
return channel is done at the same way. The signal level and the tilt of the return path
characteristic are determined using
