DVB-S Modulator

DBX-4703

Pardis DBX-4703 is a high quality cost optimized DVB-S modulator used DSNG or Satellite uplink applications. The input to the modulator comes from two ASI or E3 ports by a software selection while a Remux board can be added to the modulator to add the ability to choose a program set from the four 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. The modulator is software upgradeable to DVB-S2 AZ an offer for about 30% bandwidth efficiency.
