Adtec digital DTA-3050 (version 6.02.14) Manual - Manual (Page 71)

Modulation Targets Reference
When connecting to a modulator (QAM for cable or QPSK for satellite), the DTA3050 will automatically calculate the desired
egress rate and NIT table parameters, based on the modulation target selected.
QAM
Modulation Target 188 Byte Mode 204 Byte Mode
QAM64NTSC 5.056900 Msps 4.660400 Msps
QAM256NTSC 5.360530 Msps 4.940000 Msps
QAM64PAL 6.742500 Msps 6.213400 Msps
QAM256PAL 7.147400 Msps 6.586700 Msps
QPSK
For QPSK, refer to the following formula:
Bit Rate= Symbol Rate*(2* Viterbi * 188/204)
where Symbol Rate = Symbol Rate of the satellite carrier ♦
and Viterbi Rate = 1/2, 2/3, 3/4, 5/6, or 7/8 coding ♦
•
Manual Rate
In the event the pre-configured rates are not desired, the user can manually enter the desired rate. This is the default
mode of operation on the DTA3050. •
SMPTE-310M
Provides 19,392,568.46 bps of output over the SMPTE-310M interface.
The ASI port operates concurrently, but at a fixed rate of 19,392,568.46 bps. ♦
The ASI port can be used as a "monitor port" in this mode. ♦
