SDT 201 ARK-6 NC ATSC
The SDT series is today enriched by the SDT ARK-1, the All-in-one Transposer/Transmitter.
In fact, the ARK-1 is an Heterodyne tranposer, a Regenerative Trasmitter and a transmitter in a single hardware.
With the Echo cancellation option, perfect for Single Frequency Network, the SDT ARK is the answer for an easy move to the digitalization.
The SDT ARK-1 transmitters features a built-in SFN adapter and very advanced SWDT®(Software Defined Transmitters) technology, typical of this series of products, which allows implementing different modulation patterns — either digital or analog — (DVB-T/H, PAL, ASTC, NSTC, ISDB-T, etc.) in the same hardware. Moreover, the SWDT® technology allows selecting transmission modes in various ways: remotely, using a clean contact; via SNMP commands; via TCP/IP, using the Web graphic interface; or even via a dedicated command inserted into the transport stream.
An innovative firmware allows zero error signal processing thanks to an internal 32 bit architecture.
Functional interfaces are available for total remote control of the apparatus by means of serial protocols or TCP/IP ports. Thanks to the internal Web server the apparatus can be easily monitored and configured using a LAN connection and a standard Web browser.
Moreover, the built-in SNMP server allows performing all types of automated remote control.
