The R&S®SFD produces **s for DOCSIS3.1,
DOCSIS3.0, digital cable TV in line with J.83/A/B/C and
analog cable TV. Its downstream frequency range is
47 MHz to 1794 MHz for DOCSIS3.1 and 47 MHz to
1218 MHz for DOCSIS3.0 and TV. Within this range, the
R&S®SFD generates a DOCSIS3.1 channel with up to
192 MHz bandwidth or a minimum of 80 ltaneous
SC-QAM channels between 1002 MHz to 1794 MHz for
DOCSIS 4.0. It is possible to set the channel level, frequency, forward error correction (FEC) and constellation.
The R&S®SFD can also produce a digital, QAM-modulated
or analog TV **. The DOCSIS3.1 channel or digital
TV channel is modulated in realtime. The transmission
data can be fed in via IP or internally generated by the
R&S®SFD.
The upstream frequency range is 5 MHz to 204 MHz.
Within this range, a DOCSIS3.1 orthogonal frequency
division multiple access (OFDMA) ** can be generated
in realtime. A DOCSIS3.0 TDMA or CDMA ** can be
produced in realtime in the 5 MHz to 85 MHz range.
► FFT size or number of OFDM carriers: 4k or 8k ► Interleaver depth ► Profile constellation: 16QAM to 4096QAM, 8kQAM and 16kQAM ► NCP constellation: QPSK to 64QAM ► PLC location ► Cyclic prefix and windowing ► Exclusion band: list of unused OFDM carriers ► Continuous pilot parameter
