DOCSIS 3.1 single channel realtime generator

The R&S®SFD generates a DOCSIS 3.1 channel in realtime with flexible setting of the level, frequency, constellation and all other parameters according the DOCSIS 3.1 standard. The R&S®SFD can alternatively generate a digital realtime modulated TV signal according the J83A/B/C specification. The content can be fed in via IP or internally generated by the R&S®SFD.

Features & benefits

Signal generation in the downstream

Flexible realtime downstream modulation

The R&S®SFD modulates signals for DOCSIS 3.1, DOCSIS 3.0, digital cable TV in line with J.83/A/B/C in real time. 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 digtal TV. All parameters can be set via GUI or via SCPI remote commands. The user data to be transmitted can be fed in via IP or internally generated by the R&S®SFD from PRBS or an user file. The SFD-K202 option allows the simultaneous generation of at least 80 SC-QAM channels in the extended operating range of 1002 to 1794 MHz.

R&S®SFD GUI - Downstream configuration

Easy to use GUI allows the setup of the downstream signal with all required parameters. Predefinded values speed up the time to the first results.

Signal generation in the upstream

Flexible realtime upstream modulation

The upstream frequency range is 5 MHz to 204 MHz. Within this range, a DOCSIS 3.1 orthogonal frequency division multiple access (OFDMA) signal can be generated in realtime. A DOCSIS 3.0 TDMA or CDMA signal can be produced in realtime in the 5 MHz to 85 MHz range. The trigger function allows precise burst timing control. The R&S®SFD is an ideal solution for testing tuners, cable modems and upstream CMTS receivers.

Signal interference and distortion simulation

Simulate realistic receive conditions

For realistic signal generation, the R&S®SFD can add interference such as noise, phase noise, hum, tilt and even a defined bit error rate (BER). The signal tilt can be set positive or negative for simulation or compensation of the frequency response of a real coax CATV cable.

The impairments settings can be mixed and set independed. RF tilt settings (dB/GHz) are set on the home GUI section.

Powerful ARB generator

The integrated ARB generator can generate up to 200 MHz wide signals and is usable in the entire downstream or upstream frequency range. The maximum sample rate is 240 Msamples/s and the ARB file size up to 256 Mbyte.
