5 Construction of Systems with More then One Cascading Units
Distribution systems for satellite and broadband cable (or terrestrial) signals with more than 24
subscribers points should only be installed by authorized specialists who are familiar with the
connection circumstances and who have a selective antenna measurement equipment.
To facilitate understanding, here are some brief details of functional operation:
Within the switching matrices, signals are handled via the directional coupler and subsequently
channelled via pin-diode-switcher to the converter circuit of the subscriber. After the conversion,
the signals are collected, amplified and merged to one cable for the subscribers. Although the
switching matrices can operate via this path with an amplification of up to 20 dB, the level within
the switching matrix is considerably lower, hence the input level of the switching matrix should not
go below 45 dBμV.
The accessories, which can be used, are specifically described in the corresponding operation
instruction:
Intermediate Amplifier 5Z/NT (Art.-No. 0000/3241) and 5Z2/NT (Art.-No. 0001/3241)
The gain and the fine-tuned slope equalization of the device
are set up to compensate loss via the cable and/or
components of 12 dB at 2150 MHz.
The gain of the terrestrial signal is adjustable.
The device is DC-supplied via all four Sat-trunks. To release
the TechniRouter base unit, you can plug in the power supply
into the 5Z/NT/ 5Z2/NT. In this case, it will supply trunk amplifier 1 and 4 plus the terrestrial
amplifier and the units in front of.
The Intermediate Amplifier is not return-path-compatible.
Passive Distributor 5P (Art.-No. 0000/3242)
With a maximum loss of 4 dB, this device is used to split the
power of the signals of all satellite IF banks and the terrestrial
signal into two outputs.
The upper outputs are not DC-transmissible, but rather is
each of the side satellite outputs exists power supplied /
connected through its satellite input.
Active Tap 5/2A (Art.-No. 0000/3243)
This component is designed to tap the signals of trunk lines
several times -twice for each device- and then to feed them into
post-switched subdivisions. The trunk lines are DC-permeable
and almost loss-free; the taps are amplified and slope-equalized.
The device itself is supplied via the tap 4, but does not feed the
trunk lines. At the trunk lines of the active tap 5/2A, a device
with a power supply must be connected at all times in order to supply the switching matrices,
amplifiers and the LNB in the trunk line.
The 5/2A is not return-path-compatible.
