Overview
The UBS Universal Modulator Series utilizes the innovative UBS Universal Waveform engine, supporting all world standards for mobile and terrestrial digital broadcasts. The Universal Modulator can be software configured to support one, two or all the waveforms listed above. The user can easily switch from one waveform to another through software selection. UBS modulators can also be upgraded in the field as standards evolve. This open architecture design enables carriers to take advantage of a proven, robust platform, while designing networks to meet current and future broadcast standards. This series incorporates all of UBS high performance signal processing stages including integrated linear and non-linear pre-correctors. Full remote management and control as well as remote firmware and waveform upgrades are provided.
The unit comes in a compact metal enclosure with SMA connectors for ease of integration.
IF Output
The output is an IF COFDM signal, on a user defined frequency between 35 and 46 MHz. Inverted/non-inverted spectrum is software selectable. The spectrum bandwidth may be user configured to conform, as required, with the selected standard. The IF output can be directly interfaced to a wide range of transmitters and frequency converters.
Signal Inputs
The DVM 2010 OEM Modulator is provided with two serial DVB-ASI inputs and two serial G.703/G.704 inputs. The DVB-ASI inputs accept a MPEG-2 TS, a CMMB multiplex stream or an ISDB-T/TB multiplexed TS. The G.703/G.704 inputs are used in DAB mode and accept either NA or NI signals. The DVM 2010 can also be equipped with a GbE Transport Stream input (based on Pro-MEG CoP #3) only when a DVB-T/H waveform is selected.
For each input type, the user can select one input, or both inputs. When two inputs are selected, the modulator card supports near seamless switching to a secondary transport stream, in case the primary transport stream source fails. Two inputs are also used for the Hierarchical mode of operation.
SFN Mode
This mode provides the DVM 2010 with market leading SFN performance, with respect to basic timing accuracy and extent of the local delay offset range. The user can select either the SFN or MFN mode via the control interfaces. The primary reference clock is the external 10 MHz signal, which is applied to the 10 MHz input from a GPS. If the external 10 MHz signal is missing, the system will operate synchronized to its internal 10 MHz oscillator.
Web Interface
This feature allows remote control of the DVM 2010 via Ethernet (TCP/IP). The system is based on a Web server mounted inside the DVM 2010. The Web pages stored on the Web server are designed as a complete graphical user interface (GUI) for testing the status and setting the parameters of the modulator. The Web Interface concept is popular because remote control with this system only requires a standard PC with a network interface card (NIC) and a Web browser (Microsoft Explorer 6.0+).
SNMP Client
This feature allows remote control of the DVM 2010 in accordance with the SNMP protocol (Get, Set and SNMP traps). This remote control feature is intended for systems solutions where it is desired to integrate the control of a range of SNMP compliant equipment in a common management system.
Digital Linear and Non-linear Pre-corrector
This is recommended in order to maximize the performance of the transmitter in which the modulator is installed.
• The Non-linear Pre-corrector balances out gain and phase non-linearity in the transmitter RF power amplifier,
thereby significantly reducing the in-band and out of band intermodulation products. Optimizing the transmitter’s
performance will extend the coverage area. The performance requirement of the transmitter output filter, which is
used to suppress radiation in adjacent channels below a maximum allowed level, will also be eased.
• The Linear Pre-corrector balances out level and group delay variations that are seen across the channel bandwidth
and are caused by the transmitter mask filter and/or channel combiner filters. The linear optimization of the
transmitter’s radiated signal allows the ISDBT receiver’s channel equalizer to focus all of its correction capacity on
level and group delay errors originating from the actual transmission path.
The characteristics of the linear and non-linear pre-correction curves are set by means of an easy to use and highly intuitive graphical user interface, the UBS Corrector GUI software package (Windows compatible).
Power
Powered using a standard 12Vdc power supply (can be ordered separately).
