Product Detail

General. The new DB family of Digital Television Transmitters is fully compatible with international DTV standards (DVB-T, ATSC, ISDB, etc....) suitable for SFN (Single Frequency Network) and MFN (Multi Frequency Network) applications.

Output Power. The TDTV 40 gives a 40 W rms output power in continuous service in the whole III frequency band.

Digital Modulator. The TDTV 40 is equipped with a digital modulator (DVME-16) fully configurable, compatible with the international DTV Standards. It delivers the COFDM spectrum on a user defined frequency between 35 and 37 MHz. The spectrum bandwidth may be user configured to 8 or 7 MHz as required. Hierarchical modulation allows simultaneous transmission of two MPEG-2 transport streams.

Fully frequency agile with ultra low phase noise design. The Digital Modulator has an intuitive and easy to use interface to select the frequency without any readjustment needing.

Digital precorrector. A powerful digital linearity precorrector in the modulator combined with another one in the RF amplifier and a very selective output band-pass filter allow to obtain a perfectly clean spectrum in the adjacent channels and an excellent modulation linearity.

Phase noise. Very low phase noise oscillators allow to optimize the BER and MER performances.

Analog compatibility. The TDTV 40 is also available in analog version easily field upgradable to digital into the same rack or in dual-mode configuration locally and/or remotely selectable in analog/digital operation for maximum flexibility.

Metering. Full transmitter metering, control, setting and system diagnostic available in the front panel and (optional) remotely.

Filtering. Critical mask and non-critical mask filters available.
