DVb-S2 Modulator

DBX-4803
 

Pardis DBX-4803 is a high quality cost optimized DVB-S2 modulator used DSNG or Satellite uplink applications. The modulator is fully compatible with ETSI EN 302 307 standard and using LDPC codes presents a 30% more efficiency in bandwidth requirement compared to DVB-S system. The input to the modulator comes from two ASI or E3 ports by a software selection while Remux board can be added to the modulator to add the ability to choose a program set from the for input ports. Multiple user interfaces especially Ethernet prepare a user friendly environment to control and monitor the modulator and multiple IF and RF outputs make it easily attachable to uplinks or DSNG RF units.
