| Elti has developed .... …the new range of ARX digital repeaters for complete restoration as the DVB signal is received and re-transmitted The ARX series of regenerative digital repeaters features built-in error correction via the intelligent COFDM modulator that provides error-free retransmission of multi frequency DVB networks. The error-corrected transport stream is also available via ASI output for local re-multiplexing, or monitoring purposes. The modulator allows the repeater to function as a transmitter. Low power applications are available in compact designs up to 100 W rms; the range of LDMOS power amplifiers offers scalable solutions up to 9,6 kW rms, as air cooled or liquid cooled repeaters. the Elti advantage- 5 years warranty

Options for arx repeatersexciter The exciter is housed in a compact 19” 3U rackmount and, with the A class amplifier, provides 5 W of output power. The high sensitivity input tuner provides optimised reception of the RF DVB signal. The DVB signal is completely demodulated to MPEG-2 TS and error-corrected before retransmission in a fresh COFDM spectrum. Error-corrected MPEG-2 TS is available via ASI output for local re-multiplexing, and the ASI input allows the repeater to function as a transmitter. To optimise repeaters 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 manager software (EDM). The compact repeater includes the exciter functions, the power amplifier and output filter internally. power amplifierExternal amplifiers are available in models supplying 200 W and 400 W 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 software upload
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: 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. |  |  |
