To remain competitive, cable TV network operators must integrate this standard and ensure that both existing television channels and DOCSIS data streams are transmitted reliably.
The R&S DOCSIS Signal Analyser (DSA) from Rohde & Schwarz can be used to install, maintain and service cable modem termination systems (CMTS) at cable headends.
It is also ideal for troubleshooting complex headend problems as well as problems with cable network components that occur in the field.
The R&S DSA can be used without restrictions both in the field and at the cable headend. It analyses in the downstream and upstream (upstream in preparation) up to MER of > 50dB.
It measures without using cable modem chipsets, which typically deliver considerably poorer MER values.
To ensure interference-free coexistence of DOCSIS 3.0/3.1 and digital TV channels in cable TV networks, the R&S DSA can optionally analyse J.83/A/B and DVB-C digital TV signals. Here again users will appreciate the advantages of real-time signal processing, such as gapless fault analysis, quick result presentation and signal demodulation.
The large touchscreen makes the R&S DSA easy to use. Thanks to its flexible software option concept, the analyser offers investment protection and can be adapted to new requirements at any time.
The new R&S DSA DOCSIS signal analyser is now available from Rohde & Schwarz. It will be showcased at Cable Tec Expo in Denver from October 18 to 20.
