DT-102B
The PROMAX DT-102B Dual DVB-T Modulator is a COFDM modulator compatible with DVB-T standard. This unit includes TS-ASI input and RF output in the UHF band and features fast frequency and output level. The inputs contain services in formats such as SD, HD, MPEG-2, and MPEG-4. The internal combiner delivers a single DVB-T output with high C/N.

- Basic Functions:
The PROMAX DT102B Dual DVB-T Modulator, 2 DVB-ASI Inputs, COFDM Modulator Compatible are COFDM modulators compatible with DVB-T standard. They have TS-ASI input and RF output in the UHF band and are agile in frequency and output level. Inputs can contain services in all sorts of formats: SD, HD, MPEG-2, MPEG-4, etc.
With the PID filtering function the user can remove video, audio or data services from the original transport stream. In case of using the DT-302 as a receiver, the system allows to reduce bit rate of the incoming satellite transponders to values that can be used in COFDM.
Modulation, Forward Error Correction or Guard Interval can be set to the desired values depending on the application. This allows packing more programs in a single COFDM channel than a standard off air DTT channel. A typical configuration for a coaxial TV distribution system can be 64QAM, FEC=3/4 and GI=1/32 so that the modulator accepts the highest possible bit rate.
The dual DVB-T modulator DT-102B, includes an internal combiner that delivers a single DVB-T output with high C/N. This feature gives great robustness to the signal, allowing adding RF amplifiers in cascade during distribution with minimal loss of signal quality.
