DVB-T Exciter


Pardis DBX-8202 is a cost effective and high capacity OFDM modulator used for DVB-T transmitters. With its local or Ethernet based user interface, this modulator can be fully controlled for different OFDM modems, coding rates and channel bandwidth. tow pre-correctors (linear and non-linear) guarantee the high power transmitter work well at full load and the exciter is ready for SFN networks by its SFN adapter. the input to this modulator is through two ASI or E3 ports with software selection ability while a Remax board can be added to the system to add program set selection feature. The modulator delivers its output in low-IF or UHF bands to be ready to use in different applications.
