Product Description

The Rohde & Schwarz DOCSIS 3.1 standard is driving the trend in cable TV networks toward all-IP. The Rohde & Schwarz SFD generates a DOCSIS 3.1 OFDM broadband signal as well as the previous cable signals such as DOCSIS 3.0, digital and analog TV channels in the downstream. In the upstream, it generates a DOCSIS 3.1 or DOCSIS 3.0 signal.

The Rohde & Schwarz SFD produces signals for DOCSIS 3.1, DOCSIS 3.0, 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 DOCSIS 3.1 and 47 MHz to 1218 MHz for DOCSIS 3.0 and TV. Within this range, the Rohde & Schwarz SFD generates a DOCSIS 3.1 channel with up to 192 MHz bandwidth. The level, frequency, forward error correction (FEC) and constellation of this channel can be set. The Rohde & Schwarz SFD can alternatively produce a digital, QAM-modulated or analog TV signal. The DOCSIS 3.1 channel or digital TV channel is modulated in realtime. The data to be transmitted can be fed in via IP or internally generated by the Rohde & Schwarz SFD.
