After almost three decades in the company, Javier Esteban never stops learning. His work requires him so, in order to keep up to date with the ongoing advances in technology and meet clients' needs and expectations. Now it's time to promote ourselves in a new market.

What is your job in Televes?

I work for the Communication Infrastructures department; we provide support to clients that are installing GPON and IPTV networks. This support may be provided via telephone, video conference, and occasionally in person. New product training is one of the key aspects of our relationship with the client.

How long have you been working for this company? How was your career path in Televes?

I joined Televes in March 1991. From the very start, I have always been involved in commercial-oriented tasks. Initially, my job consisted in providing support to both clients and our commercial network. It not only consisted in providing direct support but also required market research, so for a long time I was involved in counselling and business planning tasks.

“Making ourselves known to a whole new client's profile represents a real challenge”

What is the most satisfying aspect of your job?

The group of colleagues and the continuous evolution of technology. In this respect, I have experienced the private television channels' deployment, the analogue switch-off, and the digital dividend. Now it is the Internet and the optical fibre.

And what is the hardest?

The technological evolution towards the IP world requires to be constantly acquiring new concepts. Sometimes, the approaches of this new client type can pose an important challenge.

What are, in your opinion, the essential values of our company?

The primary value of Televes lies in its commercial network. Truly committed people that need to know how to defend such a wide catalogue as Televes', which ranges from LED lighting to professional field strength meters, including IP networks.

Tell us about an ongoing project you consider important.

The department I belong to was created last year. We are working to make ourselves known to a whole new client's profile, which represents a real challenge and a great deal of effort on a daily basis. At the end of the day, it all comes to winning projects.

A real touch screen with advanced functionalities and an outstanding measurement precision

Thanks to the MOSAIQ6 touchscreen interface with gesture-based control it can be used as a smartphone or a tablet. This innovative interface takes full advantage of touch flicks (tap, double-tap, drag, slide, pinch, or spread), making it very easy to work with this high-performance meter.

MOSAIQ6 IS A multi-standard meter capable of performing both analogue and digital measurements, either IPTV, optical, or RF; furthermore, it covers all the standard range, from FM and DAB/DAB+, through DVB-T/T2, DVB-C Annex A/B/C and DVB-S/S2/S2X, to 802.11 standards for wireless local networks (Wi-Fi).

Some of the advanced functionalities are worth highlighting, such as:

Waterfall

A graphical representation of the signal in both time and frequency, to analyse transient interference and/or signal fading.

IPTV

Allows both unicast and multicast streams demodulation and analysis, not only by showing the video material, but also by displaying the total bit rate total and the bit rate per service, as well as other service parameters such as SID, VPID, AID, or the appropriate video profile.

LTE Check

Allows the analysis of the impact of interfering LTE signals on DTT channels, while identifying possible filters to be included in the installation being measured.

GPS option

With the GPS option, measurements can be displayed on a map at the very same spot where they were actually taken, thus facilitating coverage analysis.

MOSAIQ6 is equipped with a web interface accessible both locally and remotely that allows measurement management, channel plan and area modification, quality profile editing, and clone execution inter alia.

The reason is that in satellite reception there are multiple working bands (4 voltage combinations - 13 V and 18 V - and tones - 0 KHz and 22 KHz -) that cannot share the same cable. The mentioned bands are: Low Vertical Band (13 V + 0 KHz), High Vertical Band (13 V + 22 KHz), Low Horizontal Band (18 V + 0 KHz), High Horizontal Band (18 V + 22 KHz). In order to select one of them, the appropriate voltage and tone have to be sent to the LNB. In a conventional installation it is up to the satellite receiver to perform this task.

When the installation has a single satellite receiver, it is the receiver itself which requests the desired band at any time and no collisions take place. Conversely, if several receivers are installed and each of them requests a different working band, the LNB will only take the higher voltage and higher tone into account. In other words, if a receiver is sending 18 V + 22 KHz (High Horizontal Band) and another one is sending 13 V + 0 KHz (Low Vertical Band), only the receiver requesting the High Horizontal Band - the highest of the requested bands - will work properly.

One solution would be to install an IF multiband amplifier like Ref. 5363. It would feed the LNB with a fixed voltage and a fixed tone so that multiple receivers could access the appropriate channels for the selected band
