Description and Application

Overview
The UBS Universal Exciter Series utilizes the innovative UBS Universal Waveform engine, supporting all world digital standards for terrestrial broadcasting, including hybrid satellite/terrestrial systems.
The modular, state of the art design allows transmitter manufacturers and network operators to integrate the DVX 5000 into a system/network with relative ease. This open architecture design enables carriers to take advantage of a proven, robust platform while designing networks to meet current and future broadcast standards.
The Universal Exciter can be factory configured with the necessary hardware to support one, two or all the waveforms listed above. The user can easily switch from one waveform to another through software selection. UBS’ exciters can also be upgraded in the field as standards evolve.
Using the latest technology, UBS has developed a direct conversion process that allows the Universal Exciter to provide an RF output from 470 MHz to 860 MHz with superior shoulders and MER. A range of optional RF outputs including L-Band and S-Band frequencies are also available and suitable for a wide range of international frequency assignments for both terrestrial and satellite uplink systems.
Optionally, the DVX 5000 RS232 interface can be dedicated for communication with a 3rd party UPS. In this case, the exciter is configured with an extra set of SNMP parameters and will actively monitor the UPS.
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.

Signal Inputs
The DVX 5000 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. Optionally, two serial SMPTE-310M inputs can be installed.
The DVX 5000 also supports a GbE Transport Stream input (based on Pro-MEG CoP #3) only when a DVB-T/H, DVB-T2 or DVB-SH waveform is selected.
The DVB-ASI, G.703/G.704 and SMPTE-310M inputs can be automatically selected, or assigned by the user. The automatic switching provides near seamless switching to a secondary transport stream in case the primary transport stream source fails (a truly valuable feature for broadcast applications).

RF Output
The standard RF output covers a frequency range of 470 to 860 MHz in 1 Hz steps. 30 MHz to 1 GHz as well as L-Band and S-Band frequencies are available.
The output level is adjustable from -10 dBm to 0 dBm (0 dBm to 10 dBm optional), in 0.1 dB steps and the user can set the polarity of the spectrum to Inverted or Non-inverted as required.

Adaptive Non-linear Pre-corrector
The Adaptive Non-linear Pre-corrector is a superior pre-distortion solution that compensates for RF Power Amplifier non-linearities including AM/AM and AM/PM distortion and protects against IMD and spectral regrowth while maximizing EVM performance.
The complex signal processing is done in the RF domain and supports a fully adaptive operation: the feedback signal (HPA output) is compared to the exciter’s RF output signal (HPA input) in order to optimize the correction which will improve the shoulders of the RF output.
The Adaptive Non-Linear Pre-Corrector is not recommended for satellite uplink applications as it can only correct for the signal distortion from the ground-based transmitter and not the full signal path distortion. The Manual Pre-Corrector can be configured for the full system path.

Manual Linear and Non-linear Digital Pre-correctors
The manual linear and non-linear digital pre-correctors are used to maximize the performance of the transmitter in which the exciter 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 caused by the transmitter mask filter and/or channel combiner filters. The linear optimization of the transmitter’s radiated signal allows the receiver’s channel equalizer to focus all of its correction capacity on level and group delay errors originating from the actual transmission path.

Web Interface
This feature allows remote control of the DVX 5000 via Ethernet interface and is based on an internal Web server. 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 exciter. The Web Interface concept is popular because remote control with this system only requires a standard computer with a network interface card (NIC) and a Web browser (Microsoft Internet Explorer, Firefox, etc.).

SNMP Client
This feature allows remote control of the DVX 5000 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.
Optionally, the DVX 5000 RS232 interface can be dedicated for communication with a 3rd party UPS. In this case, the exciter is configured with an extra set of SNMP parameters and will actively monitor the UPS.

Machine to Machine Interface
Depending on the waveform selected, the Universal Exciter RS232 or RS485 port can be used for as a machine to machine interface. This is a valuable feature when control of an external power amplifier is required.

Internal GPS Receiver (optional)
The DVX 5000 can be equipped with an internal GPS unit. In this case, the frequency references for the exciter and upconverter are derived from the internal GPS receiver.

DVB-S/S2 Receiver (optional)
With the addition of an integrated DVB-S/S2 Receiver, the DVX 5000 can demodulate an incoming signal and rebroadcast at a different frequency.
