EXPERT OPINION

While the elements that support an installation of SMATV (5-2150MHz) could be used in a CATV facility, upside down do not add up.
And with the coaxial cable it is the same: inner core made of copper-clad steel, typically used by cable operators, in general terms is not recommended for DTT distribution networks and SMATV.
The difference between a cable with its inner core made of steel or made

of copper, results in a remarkable difference in conductivity, strength and, above all, its resistance to corrosion.
Effectively, at high frequencies, the outer layer of the copper-clad steel performs as a copper conductor; nevertheless this conductivity is being lost when environmental conditions start to deteriorate the steel.The joints between devices are sensitive to these circumstances, precisely where the

impedance matching is more critical, and from which depends largely, the quality of the digital signal to be distributed.
Conclusion: Although the legislation allows the use of copper-clad steel in operator networks, the copper is ideal for SMATV networks and, ultimately, to all those networks wanting to keep unchanged its characteristics

Until it clears up...

Televes has always stood for the care and attention provided to the installer. Evidence of this is this picture taken at the recent convention Fenitel in Vigo, sponsored by Televés. It can be seen as installers walk protected from the rain with promotional Televes’ umbrellas. 

Eduardo Castro, as the person responsible of the Laboratoy of Certification of Televes Corporation, ensures compliance of every market for the products launched by the companies of the Group. But the laboratoy goes far beyond, subjecting the products to demanding tests to ensure the higuest quality and a useful lifecycle superior to the competition.
What role does Ladetel play inside of Televes Corporation?
From the product design stage, Ladetel provides the knowledge, judgment and legal and regulatory requirements for the product to be marketed. During the different stages of industrialization, Ladetel is responsible for carrying out tests and experiments to ensure compliance with regulations.
What have been the most important milestones in terms of management and certification?
Undoubtedly the most important milestone was the product CE marking without having to resort to external laboratories. It must be noted that the CE compliance involves two European directives, the
 

Electrical Safety and Electromagnetic Compatibility..

What kind of services are offered to external customers?
The tests we offer to external customers are the same we offer to the group companies. Moreover, in certain cases we can rent the measuring equipment or even make tests in customer facilities, especially if they already have trained staff.
Under what quality standards does Televes Corporation work?
We pursue the quality standard management ISO9001. In the medium-term plans the implementation of ISO17025, exclusive for testing laboratories, is contemplated.
How important are certifications to guarantee product quality?
Certification tests detect possible disturbances that the product can cause on other equipments (emissions) as well as possible shocks received by nearby equipments (immunity). When a critical point is detected during electromagnetic compatibility (EMC) testings, sooner or
 

To ensure to the highest a proper long-term operation of the product we focus also on resistance, vibration, UV exposure for plastics, corrosion cycles testings, etc.
In terms of quality, at what level are Televes Corporation products in the international context?
The complete product range of Televes is subjected to the most rigorous testings, even above regulatory requirements. To give an example, equipments that must have a resistance of 2000 V, in Ladetel we test them to 6000 V; and equipments that according to regulations require withstanding 4000 V of electrostatic discharge are tested to 10,000 V.
What are the major plans of Ladetel for the future?
In the short and medium term, the international projection of our laboratory. We are in a good training provision to undertake the most demanding certifications as UL and TÜV markings.
In the long term, the ENAC accreditation by implementing ISO17025

The measurement of attenuation in RF networks requires the availability of an item that generates the RF signal throughout the operating band. Meter and Generator must be calibrated together in order to give accuracy to the final result of the test.

The ICT-2 spanish legislation requires the measurement and recording of attenuations in CATV networks, as well as signal levels, C/N ratio and BER for signals of MATV/SMATV, in all outlets of the facility.
For MATV/SMATV the measure is “direct”, whereas for CATV it is necessary to perform an external calibration. To do this it must be recorded firstly the signal level at the output of the noise generator (Ref 5930), frequencies to be measured and, subsequently, recording the signal levels in the outlets at those same frequencies. Upon completion of the exportation of the measured values to the PC, it can calculate the difference between the two signal levels thus obtaining the value of attenuation.

With the new meter H60 the whole process of attenuation measurement is simplified, significantly reducing the time spent on it and the probability of a human error.
For direct measurement of attenuations, set frequencies to be measured and calibrate the noise generator automatically with the Meter H60. Then, attenuation measures are shown immediately on the Meter. This process is faster, easier, and allows to confirm “in situ” if attenuation measurements are consistent with the desired values or, which is the same, according to the project.
He number of frequencies that can be configured ranges from five to ten; all of them displayed in the screen of the Meter. It is possible to define typical ranges like 5MHz, 862MHz, 950MHz

and 2150MHz.
This functionality can have many applications: from measuring the attenuation of a roll or a piece of coaxial cable, up to obtain the response of a tap, splitter, ... etc.
It is possible to save multiple configurations of attenuation measuring in its memory to be used subsequently, being enough pressing a single key to keep stored the records of each outlet performed at different frequencies.
As usual, this function performed by the H60 meter has been inspired by the requirements of installers, and shows once again the ability of Televés in customizing the product to market needs

At the very beginning, Televes was focused on the production of metal structures. One of these structures were the antennas associated afterwards with the electronic devices that we produce nowadays. The other one where the baggage racks, commonly referred to as roof racks.

In today’s world of smartphones and full connectivity, Field Strength Meters also have to keep up to the new trends. With the new H60 Televés Meter you can send your measurements, change channels and view its screen in real time by using your iPAD. Furthermore, measurements can be stored for days.
Doubtless the H60’s remote management represents a breakthrough in the measuring field 

INSNET, installer working in Palma de Mallorca, has carried out a deep reform on the headend of the AYA hotel, which is situated in Palma’ Arenal beach, one of the preferred destination for German tourists.

The headend consists of 4 DTT processors and 9 DVB-S2/COFDM transmodulator; and distributes services that exceed forty five ones. And, as we recommend in installations subject to the marine environments, also in this case the installer is making use of parabolic dishes from the QSD range.
