Rohde & Schwarz presents DOCSIS analyzer with new upstream analysis option at ANGACOM

In October 2017, Rohde & Schwarz launched the popular R&S DSA DOCSIS signal analyzer to enable realtime analysis of high-speed DOCSIS 3.0 and DOCIS 3.1 signals. Now the company is unveiling the new R&S DSA-K1500 upstream analysis option for cable modem testing. Rohde & Schwarz is presenting the new solution from June 12 to 14, at ANGACOM in Cologne, booth R50, hall 8.

Cable network operators can use the compact analyzer to check whether their networks and network components meet DOCSIS requirements. With the R&S DSA-K1500 option, the analyzer now provides additional functions for analyzing DOCSIS 3.0 and DOCSIS 3.1 upstream signals. The R&S DSA together with the R&S SFD DOCSIS signal generator from Rohde & Schwarz forms a compact test system for performing ranging tests on cable modems to provide information about the signal quality in the upstream direction. The handy, user-friendly R&S DSA has top-notch RF characteristics. Thanks to its low inherent error, it is ideal for measuring the modulation error ratio (MER). It delivers reliable performance for detailed signal analysis. First customers included industrial companies and cable network operators.

The R&S DSA from Rohde & Schwarz is perfect for installing, maintaining and servicing 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 is the only DOCSIS analyzer that can be used without restrictions both in the field and at the cable headend. With the new R&S DSA-K1500 option, it can now simultaneously analyze downstream and upstream signals. It achieves MER values greater than 50 dB because demodulation is handled by high-performance FPGAs instead of cable modem chipsets, which are typically designed for lower MER values. With its exceptionally low inherent error, it offers the best MER performance of all realtime DOCSIS analyzers on the market.

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 analyze J.83/A/B and DVB-C digital TV signals. Here again users will appreciate the advantages of realtime signal processing, such as seamless error analysis, fast result presentation, signal demodulation and output.

The R&S DSA features a large touch display for easy operation. Thanks to the flexible software option concept, the analyzer can be adapted to new requirements at any time. That’s investment protection.

The new R&S DSA-K1500 option for the R&S DSA DOCSIS signal analyzer is available now from Rohde & Schwarz.
