Description
La Serie Amplicadores DTKOM contiene centrales profesionales de calidad,
en las que se combinan dos amplicadores de banda ancha independientes
para una distribución interior. Esta Serie ha sido diseñada para sistemas
de distribución multicanal RF, en los que la entrada puede ser la bajante
principal de cable o la salida de una cabecera MATV/SMATV/CATV. La Ref#
451282 es un amplicador de gran potencia y alto nivel de salida con un
ancho de banda RF de 1002MHz, con capacidad para funcionar en dos
bandas separadas en 36/49MHz. El retorno es congurable, pudiendo ser
activo o pasivo.
Las Ref# 451282 ofrece una ganancia de 30dB-40dB, seleccionable por
el usuario. Dispone de atenuador-ecualizador 18dB, y de regulador-
preacentuador 10dB.
El canal de retorno gana 28dB en modo activo. Dispone de atenuador 18dB.
Se dispone de test entrada-salida a -20dB para testear el equipo en
funcionamiento.
La unidad puede comandarse:
Vía local con un programador externo 7234 permite testear, modicar y
guardar los parámetros de la unidad; puede asignársele una dirección 1...
254.
Vía remoto según los estándares B_LAN; mediante órdenes vía cable,
permite testar, modicar y guardar parámetros de la unidad.

The DTKom Series Ampliers are professional quality, completely
self-contained, two-way broadband indoor distribution ampliers
designed for multi-channel RF distribution systems where the input
source is a cable drop or the output of a MATV/SMATV/CATV headend.
The Ref# 451282 is a high output level, power doubling amplier,
with an RF bandwidth of 1002MHz, equipped for 2-way operation
with a 36/49MHz split that can operate in passive or active return
congurations.
Ref# 451282 has a user selectable gain of 30dB or 40dB and has an 18dB
attenuator/slope control and 10dB of regulator-tilt control.
Return gain is 28dB when in active mode and has an 18dB attenuator.
Two -20dB test points are provided to allow testing without interruption
of service.
The unit can be controlled:
Via local - With an external programmer Televes part number 7234,
allowing the technician to test, modify and save unit parameters; it can
be assigned an address of 1... 254.
Via remote - According to B_LAN standards by commands via
distribution cable network, authorized user to test, modify and save
parameters of the unit.
The unit 451282 has a tuner and can test (via local and via remote),
channels according to ITU standard J.83 QAM B.
The DTKom Series ampliers incorporate a built-in switched 120/230V~
power supply and are characterized by their exceptionally low power
consumption for a long and trouble-free operating life. The cast Zamak
