      產品詳細介紹Product Introduction

      The best in realtime

      Only the highest signal quality ensures maximum throughput. The R&S®DSA DOCSIS® signal analyzer has been designed to support users by ensuring the highest signal quality. DOCSIS is the standard for transmitting IP data within hybrid fiber coaxial (HFC) cable TV networks. The new DOCSIS 3.1 standard supports unprecedented data rates, meeting the demand for increased data throughput.

      The R&S®DSA allows precise, gapless signal analysis of DOCSIS 3.0, EuroDOCSIS 3.0 and DOCSIS 3.1 signals on the physical layer in realtime. A user can detect effects that degrade signal quality, e.g. ingress, reflections and laser clipping. With its dual receivers, the R&S®DSA analyzes downstream and upstream signals. The frequency spectrum and key signal characteristics are displayed in compact overviews and diagrams, providing conclusive information about the signal quality.

      In addition to DOCSIS signals, the R&S®DSA can analyze digital TV signals such as J.83/A/B/C and DVB-C. Although IP data transfer is consuming more and more transmission capacity, digital TV transmission continues to play an important role in cable TV networks. The R&S®DSA can analyze digital TV, helping users ensure interference-free coexistence of DOCSIS and digital TV channels.

      Convenient operation via the 10.1" touchscreen, intuitive pictograms and logically structured menus allow even less-experienced users to operate the instrument after a quick introduction.
