Input Splitter
Link type 74089 is applied if the loop port is not used. Splitters with a bridger
Link type 74089 is applied if the loop port is not used. Splitters with a bridger
provide the largest attenuation at the amplifier input.
Diplex Reverse Filters
Three diplex reverse filters type 75110 with the requested filter frequency are used. If
Diplex Reverse Filters
Three diplex reverse filters type 75110 with the requested filter frequency are used. If
the reverse path is not used, three links type 74089 are mounted.
AUX Plug-in Field (Equalizer, Attenuator)
In order to adjust the amplifiers to the cable, it may be necessary to insert an
AUX Plug-in Field (Equalizer, Attenuator)
In order to adjust the amplifiers to the cable, it may be necessary to insert an
equalizer type 74100-xxx or an inverse equalizer type 74190-xx at the input. If no
equalization/attenuation is requested, 0 dB link type 74069 is inserted.
Input Equalizer and Attenuator 3-pin
Use type 77140-xx (0-18 dB in 1 dB step) to select attenuation and equalizing at the
Input Equalizer and Attenuator 3-pin
Use type 77140-xx (0-18 dB in 1 dB step) to select attenuation and equalizing at the
input.
Interstage Attentuator
The gain can be adjusted with an interstage attenuator type 74150-0x (2, 4, or 6 dB) in
Interstage Attentuator
The gain can be adjusted with an interstage attenuator type 74150-0x (2, 4, or 6 dB) in
order to minimize the influence on the system values. Use link type 74069 for 0 dB.
Interstage Splitter for Gain Definition
If an asymmetric splitter (bridger) is used, the low gain port is obtained at output 2
