The television transmitters belonging to this series areavailable in different versions for the VHF I, VHF III and UHFfrequency bands and in different configurations that permitinstallation and operation in sites with different characteristics andenvironmental conditions. The final amplifier consists of distinct amplifiers operatingautonomously and combined in such a way as to guarantee full redundancyof the stages.
Each individual amplifier is, in turn, internally redundant and poweredindependently to ensure high reliability and practicality inmaintenance operations. Microprocessor circuits carry out continuous control checks and providefor the visualization of all operating parameters on local controlpanels or by means of a TCP/IP port with integrated Web server. Thesame data is transmitted to rear-mounted connectors for remoteinterfacing. The great efficiency of power supply circuits guarantees low powerconsumption and a high degree of MTBF.
The third generation exciters, available in both DVB and ATSC standardswith their wide array of options, and the excellent quality of thesedigital transmitters ensure high performance capability and open up newprospects for the realization of DVB-T and ATSC networks in both SFNand MFN applications.
