Compact EGC Amplifier Model 93250
Description
The Compact Electronic Gain Control (EGC) Amplifier Model
93250 combines powerful performance with ease of use to
meet the growing demands from operators for advanced
products. It provides advanced features and benefits to help
operators reduce operating costs by streamlining amplifier
deployment and configuration and is especially well suited for
network upgrades due to increased reverse gain.
93250 combines powerful performance with ease of use to
meet the growing demands from operators for advanced
products. It provides advanced features and benefits to help
operators reduce operating costs by streamlining amplifier
deployment and configuration and is especially well suited for
network upgrades due to increased reverse gain.
The amplifier performs to 1 GHz in the forward path and can
be configured electronically, using a handheld programmer
terminal, for rapid initial set-up or for adjustments that arise as
network requirements shift. All settings are done without
interrupting service, an especially important capability in
networks which are delivering Voice over IP (VoIP) services. Settings for the EGC amplifier can be
established or modified using a handheld programmer terminal. Settings from one amplifier can be uploaded
to the handheld programmer terminal for downloading to other amplifiers in order to streamline their
configuration. Different forward gain settings can be obtained in the amplifier, enabling it to support several
different applications within the network allowing a single amplifier model to help reduce inventory and lower
costs.
The number of amplifier plug-ins is reduced to a minimum to help operators keep inventory and costs down.
The full range electronic attenuators and equalizers offer improved versatility and make it possible to achieve
the same adjustment range as with conventional plug-in or potentiometer solutions. Plug-in diplex filters are
used to determine the forward/reverse band split.
To meet future demands for more bandwidth, the amplifier offers an electronic 862 MHz to 1 GHz field-
programmable bandwidth extension, as well as a reverse path that can be upgraded to 200 MHz.
The Compact EGC Amplifier Model 93250 can be configured with a Scientific Atlanta status monitoring
transponder (SMC or HMS) to enable remote monitoring of critical amplifier parameters and remote control of
the built-in 3-state reverse switch. All amplifier settings are remotely addressable via the ROSA™ Element
Management System to help reduce truck rolls and associated costs.
