Description
General
The Output amplifier OPA 8500 amplifies TV/QAM/FM signals, which are present on the inputs of the OPA 8500. The OPA 8500 supplies the following coaxial or optical downstream distribution system with the amplified signals. The RF-output, RF-inputs and two RF-monitoring outputs operate in the frequency range 47 ... 862 MHz. The OPA 8500 is built with two parallel hybrids. Two equivalent mains connections are available via the rear-panel.
The OPA 8500 is used in a combining network. The combining network consists of the following functional groups:
RF-combiner RFC 8500/5
l
RF-combiner RFC 8500/4
l
1 HU Mounting frame MIO 8500 (for maximal 3 RF-combiners)
l
Output amplifier OPA 8500
l
The OPA 8500 has 10 RF-inputs and one RF-ouptut. The RF-inputs are meant:
for TV- or QAM-signals (4 RF-inputs)
l
for FM-signals (4 RF-inputs)
l
for pilot frequency signals or wobbler (2 RF-inputs)

Output amplifier OPA 8500
The OPA 8500 is built asa1HU19"slide-in module. The front-panel contains:
the display
l
the LED’s
l

l
two RF monitoring outputs
l
The rear-panel contains:
2 x mains connection

Cooling The SAI 8500 is cooled by convection.
Power supply
The OPA 8500 can be operated with the following mains voltages:
l
115 VAC
l
230 VAC
The power supply is of redundant design. For back-up purposes there are two mains connectors available on the rear-panel. The OPA 8500 can be integrated into a back-up supply system.
ATTENTION: Before operation make sure that the mains voltage matches the
supply voltage indicated on the device.
The mains fuse is located beside the mains socket. The OPA 8500 does not have a mains switch. To disconnect the OPA 8500 from the mains, both mains plugs must be pulled out of the device. Both mains voltages (mains 1, mains 2) can be monitored through alarm messages.

Control
General For controlling there are the following possibilities:
Keypad and display on the OPA 8500 (see chapter ”Menu operation”)
l
10 Mbit Ethernet-interface (Software option “Network Access Control”)
l
RS 232 Interface for stand-alone devices (Software option “Network Access
l
Control*)
Putting into operation
Remote control in a network (software option)
The OPA 8500 can be remote controlled via the Ethernet interface or RS232 interface. A standard WWW-browser with TCP/IP protocol (e.g. Internet Explorer) is to be used. The remote control can be disabled on the OPA 8500.
Monitoring
General For monitoring there are the following possibilities:
keypad and display
l
LED’s “ f ” and “OUT” (see interfaces and operating elements)
l
Monitoring outputs “RF m”
l
10 Mbit Ethernet-interface (Software option “Network Access Control”)
l
RS 232 interface for stand-alone devices (Software option “Network Access
l
Control”) Remote monitoring interface ”ALARMS”
l
History / operation log (see menu operation)
l l Status display (see menu operation)
Remote monitoring interface ”ALARMS”
On the remote monitoring interface ”ALARMS” the status messages ”ALARM” and ”WARNING” are signalled via two floating double-throw contacts. To the floating double-throw contacts external error indicators ( e.g. siren, lamp) can be connected. The pin-assignment is shown in the section ”Interfaces and operating elements”.

Amplifier
Block diagram
The amplifier consists of two parallel hybrids (Amplifier A, Amplifier B). The current consumption and the temperature of both hybrids are monitored. For monitoring the temperature an alarm and warning threshold can be set. The nominal temperature range of the amplifier is -10oCupto+55oC.

RF combiner
Putting into operation
With the passive and broadband RF-combiners the RF signals can be combined int eh frequency range from 47 MHz up to 862 MHz. There are following types of RF-combiners:
RF combiner RFC 8500/4 four inputs, one output
l
RF-combiner RFC 8500/5 five inputs, one output
l
The RF-combiners are mounted in the mounting frame MIO 8500. The MIO 8500 measures 1 HU and 19”. It can contain up to three RF-combiners.
