The TMQAMasi modulator is a professional quality, modular, digital headend compo-
nent designed to provide optimum performance with minimized rack space require-
ments. This model accepts an MPEG-2 transport stream (with or without scrambling),
adds the desired Forward Error Correction (FEC), and outputs an IF signal at 44 MHz
modulated by the input data stream using Quadrature Amplitude Modulation (QAM).
The modulation method selected can be 16QAM, 32 QAM, 64QAM, 128QAM or
256QAM. This IF signal would normally be input to a Drake Digital upconverter to
translate it to the desired operating channel frequency.
Features
• Convenient front panel buttons and display allow easy setup of operating parame-
ters.
• Forward error correction encoding supports DVB or Digicipher II® modes.
• Provides automatic or fixed clock modes.
• Built-In PRBS test mode.
• Null packet stuffing is provided as needed in the internal fixed clock mode.
• Designed to interface with Drake Digital DUC550 or DUC860 up converters.
• Made in the U.S.A.
