Description and Application

The DVMP 5000L from UBS is a compact, test solution, for the development and quality control of DVB-T and/or DVB-H systems. A key factor in the product’s success is the quality of its coding and modulation process. The modular design makes the unit highly flexible and easily adaptable to provide the exact features required in a specific application.

The performance and flexibility of the DVMP 5000L allows it to excel in any application related to DVB-T/H modulation.  The core function of the DVMP 5000L is to modulate a MPEG-2  transport stream (input) onto an DVB-T/H compliant OFDM spectrum (output) in accordance with the rules for channel coding and modulation specified in the ETSI DVB-T and/or the DVB-H standards (EN 300 744 and/or ETSI EN 302 304)

RF Output – L-Band Version
The DVMP 5000L delivers the COFDM spectrum on a user defined L-Band frequency from 1665 MHz to 1680 MHz, in steps of just 1 Hz.  The output level is adjustable from -10 dBm to 0 dBm with a step size of 0.2 dB.  The user can set the polarity of the spectrum to Inverted or Non-inverted as required.  The spectrum bandwidth may be user configured to 8, 7, 6 or 5 MHz as required

The DVMP 5000L has two MPEG-2 inputs (ASI format)), which 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).

IF Output
The DVMP 5000L has an IF output, where the same COFDM signal is available at 36 MHz (default), or at a user defined frequency between 35 MHz and 48 MHz.  The IF output can be directly interfaced to a wide range of  transmitters and frequency converters.
