The transparent digital transmodulator,
referred to as the TDT+, turns the
information contained in a satellite
transponder for example (QPSK modulation)
and a maximum bandwidth of 36 MHz into a
VHF or UHF channel (QAM modulation) and
a maximum bandwidth of 8MHz (depending
on the selected QAM modulation).
The TDT+ performs the QPSK demodulation
of the input channel (transponder) obtaining
a MPEG2-TS signal (MPEG2 Transport
Stream). Then the TDT+ performs a QAM
modulation of this MPEG2 signal, which
implies a modulation change of the digital
information (digital transmodulation).
The input channel, the input signal
parameters and the output channel
paramters are selected using the
programmer ref. 7234 which is connected to
the front of the device.
It is also possible to control the unit using a
PC as explained in section 7.
The TDT+ disposes of an IF input and
output in the upper F connectors so as to
enable the input of the signal into various
TDTs +. It also allows us to power a
converter via the signal input (13/18 V). In
the case of a shortcircuit, the front LED
flashes on and off, stopping when the
shortcircuit is over and when the 13/18V
is back in the connector. It also has an
input and output RF connector, for the
channels to be mixed before they are
amplified.

It disposes of two input signal connectors so as to mix the channels
that come from two systems. If only one of the inputs is used, it is
advisable to load the unused input with 75 ohm, ref 4061.
It disposes of
n output connector and a Test socket (-30dB)
located at the top of the front panel.
The amplifier is powered with 15V via a cable, the same type as
that used to power the other modules of this system .
Amplifier with zamak chassis, its gain can be configured by the
installer.
It can be used as a headend or line amplifier in CATV systems.

frequency and symbol rate (baud rate), as
well as the LNB power selection.
The input frequency range is 950-2150 MHz,
and the symbol rate is 1.500 to 45.000
Kbaud.
The power options for the LNB are 0V, 13v
22 KHz, 13v, 17v 22KHZ and 17 v.
To change the frequency or symbol rate,
press the key until the cursor is over the

To change the selection of the LNB power,
press the key until the required parameter

selected in section 5.2.a, as it will be
selected automatically according to the
automatic connection table.
Otherwise (in normal mode), 16, 32, 64, 128
or 256QAM may be selected. It is important
to bear in mind that the maximum symbol
rate in QAM is 7.2 Mbaud.
For example:
Input symbol rate: 27.5 Mbaud
Input Viterbi code: 3/4
Selec. Modulation Format: 32QAM
Symbol rate in 32QAM=
(27.5 x 2 x 3/4)/5= 8.25 Mbaud
This symbol rate is higher than the
maximum of 7.2 Mbaud, meaning that a
higher modulation format must be chosen:
64QAM or 128QAM. For example, if we
select 64QAM, the symbol rate for the
previous values will be 6.875 Mbaud, and
5.893 Mbaud for 128QAM.
The next parameter, spectrum inversion (IQ),
makes it possible to change the IQ
modulation format to normal or inverted.
Output level with range from 00 to 99.
To change the QAM modulation order,
spectrum inversion and output level, press
the key until the required parameter
flashes. Change using the and keys.
c.- Measurement menu
This menu shows the following information:
Estimation of the CBER (bit error rate of the
channel, before the decoder of Viterbi, has
to be greater than 10E-2 for a correct
demodulación).
MONITOR
CBER: 2.0E-4
QAM: 6.875Mb
Temp.:42.0ºC
The first two digits correspond to the mantis
and the last corresponds to the exponent.
For example:
2.0E-4
this indicates an error rate of 2.0 x 10-4.
The next parameter shows the QAM symbol
rate of the output signal. This figure is useful
when programming some IRDs.
If the QAM modulator is not connected, the
message “QAM: unlock” will be shown.
Internal Temperature shows the temperature
inside the TDT+ module in Centigrade.

The TDT+ allows a 4-digit access code to be
used optionally, using values outside of the
input frequency range (0000-0949 and
2151-9999), thereby allowing for 8799
different access codes.
The access code for the TDT+ operates as
follows:
- To enter an access code, an input channel
must be saved in the range of unused
frequencies (2151-9999). Pressing the
key for approximately 3 seconds will bring
up the following screen:
- To check the password, the key must
be held down for approximately 3

7.- CONTROLLING THE DEVICE
This version of the TDT+ permits
configuration and control from a PC, both
locally and via remote control.
a.- Local control
The user must have the "Headend
Management" program version 2.1.0 or
upper and a special cable (provided with
this program) that connects a PC serial port
to the "PRGM" connector of the TDT+.
Using the program, the user can configure
and read all of the parameters, as well as
check that the device is working properly.
Below is a configuration screen of the TDT+.
it is possible to see that the configurable
parameters are the same as those that can
be configured using the remote control.
b.- Remote control
As well as the program previously
mentioned, it is necessary to have a
Headend Control module (ref. 5051 or 5052)
and the corresponding modem connected
to the telephone line. Once communication
has been established with the headend
control, you will be able to access all the
controllable devices that have been installed
in the headend.
In this case, it is essential that every element
is programmed using a different device
address (address RS485) between 1 and
254.

gap (approx. 3-5 cm) at the top of the Rack.
The new air will enter through the bottom of
the rack, fig 3.
9.1.- Installation of the rack with
ventilation facilities.
To facilitate the renewal and circulation of air
inside the rack, and thus reduce the
temperature of the units thereby improving
their characteristics, it is advisable to place
2 ventilation units of 25W, particularly when
the rack with the TDT+ is located in warm
place, with a temperature higher than 40°C.
These ventilators will be placed on a tray,
that is screwed onto the top part of the
Rack, fig. 1 and 2, and in this way the
ventilators will be able to extract the air from
the TDT+ and will be able to expel it via the
Subracks
