Descriere

The MO-280 is a professional SFN/MFN DTMB modulator fully compliant with the GB20600-2006 and the GY/T 229. 1-2008 standards contained in a 19" 1U chassis. The unit has two serial ASI MPEG-2 TS inputs, one 10 MHz GPS reference input and one 1pps GPS reference input. The GPS inputs are used in combination with the Second Frame Initialization Packet (SIP) embedded in the transport streams for SFN synchronisation purposes.

In MFN mode, the MO-280 is able to work with any incoming bit rate as long as the net bit rate resulting from dropping all NULL packets present in the stream is strictly lower than the value given in the DTMB specification for the modulation parameters in use.

Two test modes are available in the MO-280 DTMB modulator, single tone output and test TS generation.
