1.1 Description

The arrival of Digital TV boosted the installation of Direct To Home satellite TV
systems. The continuous release of new packages or 'bouquets' and services such as
Internet, affordable connection fees and subsidised boxes require new simplified
installation procedures that are capable of guaranteeing received signal quality.
Because of the range of services offered by modern satellites and the ever
increasing signal density, different tests have been developed from those available in
classic satellite detectors and meters. There is a need to discern among different
satellites, to adjust the skew and to check digital signal quality.
The PRODIG-1+ responds to the need for an installation tool that might allow
making the job fast and including all necessary measurements to secure quality of
reception. Nevertheless, measurements are information that needs to be compared with
known references. Comparison takes time in order to analyse the data for each
installation.
The PRODIG-1+ has been designed to guarantee the maximum number of
installations with the best possible quality, thereby helping the installer to evaluate the
results.
The instrument directly determines if signal quality is of a sufficient level for
reception. This is done on the basis of the internal BER measurement and the signal
noise ratio (SNR).
The PRODIG-1+ processes all the information and gives to the installer just the
information he requires , thereby making his work as easy as possible.
The PRODIG-1+ is a very easy to use instrument that guides the user through 3
steps, enabling the desired satellite to be located, guaranteeing its identification and
accurately adjusting the receiver antenna to obtain the best possible signal quality.
In the PRODIG-1+ , the ultimate measurement to determinate the signal quality is
the Signal/Noise ratio (SNR), this is directly related to the BER (Bit Error Rate). The
instrument displays 'BER' when the BER is < 2x10E-4 (equivalent to good quality) and
'ber' when the BER is > 2x10E-4 (equivalent to poor quality). This threshold may be
reprogrammed according to the signal quality level specified by each operator.
