Description

LOW POWER TV TRANSMITTERS

Low Power Compact Transmitter

The New EARK Universal Driver can be configured with just software selection and implements DVB-T/T2, ATSC, ISDB-T, DTMB, ATV modulations.

It can be used as a Transmitter, Gap Filler, Heterodyne Transposer, Regenerative Transmitter, Dual Cast Analog + Digital Multistandard

EARK UNIVERSAL DRIVER allows the selection of operation modes and total remote control:

• remotely, using a dry contact;

• via TCP/IP, using a LAN connection, web graphic interface, and a standard web browser

• via built-in SNMP;

• via a dedicated command inserted into the transport stream.

The New EARK Universal Driver optimizes the investments of both international broadcasters, reducing the transmitter types, and national broadcasters, thanks to its versatility in operation modes and configuration.

The New EARK Universal Driver is future-proof and guarantees a perfect upgrade path for new modulation schemes that will be delivered.

The previous series EARK can be upgraded to the new features.

New improved features compared to the previous series: Ÿ

  • Color large-sized display with important monitoring measures: spectrum, constellation, etc
  • Upgrade through USB Ÿ and OTA
  • Licensing upgrade
