RS SFD DOCSIS 信号发生器

CLGD
下行信号生成
灵活的实时下行信号调制
R&S@SFD可实时调制DOCSIS 3.1、DOCSIS3.0以及数字有线电视(根据
J.83/A/B/C)信号。下行信号频率范围分别介于47 MHz至1794 MHz (D0CSIS 3.1)和
47 MHz 至1218 MHz(DOCSIS3.0和数字电视)。所有参数都可以通过图形用户界
面或SCPI远程命令设置。需要传输的用户数据可以通过IP馈入，或由R&S@SFD 根据
PRBS 或用户文件内部生成。SFD-K202选件能够在1002 MHz至1794 MHz扩展操作
范围内同时生成至少80个SC-QAM通道。

主要特点

下行：47 MHz 至 1218 MHz/1794 MHz；上行：5 MHz 至 204 MHz

DOCSIS3.1、DOCSIS3.0、J.83/A/B/C 和模拟电视

信号干扰及失真

在 1002 MHz 至 1794 MHz 范围内同时生成至少 80 个 SC-QAM 通道

200 MHz 的任意波形发生器带宽

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
