Elti has developed .... ...the new range of SKY digital transmitters to integrate 50 years of experience with the latest digital technology The SKY series of digital transmitters combine Elti’s reputation for robust equipment with the latest digital technology: a COFDM modulator providing DVB-T streams in 2k and 8k mode, and DVB-H stream in 4k mode. They are scalable and flexible, supporting applications from 500 mW up to 9,6 kW rms; low power applications are available in two compact versions, up to 5 W rms in 3U and up to 100 W rms in 4U and combined with the Elti range of power amplifiers they offer transmission solutions up to 9,6 kW rms, as air cooled or liquid cooled transmitters. the Elti advantage5 years warranty Fully compliant with EN 300 744 (DVB-T) and EN 302 304 (DVB-H) Full hierarchical mode support IFFT 2k, 4k and 8k mode LDMOS technology Remote management and control via TCP/IP, HTTP and SNMP interface Settings fully adjustable by software Flexible, scaleable and upgradeable Plug-and-play installation Adaptive digital precorrection and clipping function
Options for sky transmittersexciter The exciter is housed in a compact 19” 3U rackmount, and, with the A class amplifier, provides 5 W of output power. The built-in COFDM modulator features two inputs with the option of two more, and provides 2k, 4k and 8k IFFT operation mode. If the primary transport stream source fails the exciter can switch between the two ASI inputs manually or automatically. Unit is supporting MFN and SFN operation, featuring an integrated GPS receiver (optional). To optimise transmitter performance a digital precorrector is included with an option of adaptive digital precorrection (optional) to correct linear error and non-linear distortion of RF power amplifiers. Various interfaces provide connectivity to the supervisory systems and a remote/local connection to the PC base that features user friendly Elti Device Managing software (EDM). The compact transmitter includes the exciter functions, the power amplifier and output filter internally. power amplifierExternal amplifiers are available in models supplying 200 W rms and 400 W rms of output power. All amplifiers are designed for broadband and employ LDMOS technology to guarantee linearity, compact design and high efficiency. Self-protection circuits assures continuous operation and uninterrupted service.
control and monitoringThe integrated control unit provides full control over the assembly and additional options/features. Control software EDM (Elti Device Manager) with a user friendly graphic interface comes as standard for all Elti DVB-T and DVB-H products. It features: - Control of all parameters related to operation
- Password protection and access control
- Measurement and display of power, voltage, current, temperature
- Alarm
- Management of machine history
- Save and restore function
- Remote upload of software
The control software offers the same comprehensive functionality whether used locally or remotely via TCP/IP, SNMP or GSM networks. External connections are provided by: - Ethernet LAN/WAN for local/network access
- RS 232 for local access
The central control unit allows integration into ELTI ETRC telemetry system or other supervisory systems. It also offers the control of third party equipment and integration into a single system at the transmission site. |  |  |
