Protocol analyser meets DOCSIS 3.0 and 3.1 standards

Multiple systems operators (MSOs), chipset manufacturers, product developers and certifications bodies can use it to quickly find and correct trouble spots in order to maintain the highest quality of service possible.

Optimised for real-time signal processing with FPGA technology, the DP-1000 analyses up to 32x8 single or bonded US/DS channels (DOCSIS 3.0) and 2x1 OFDM US/DS channels (DOCSIS 3.1), and includes numerous channel-filtering, demodulation, triggering, display, and upgrade features.

As a passive sniffer between CMTS and CPE devices, the analyser silently captures and filters DOCSIS MAC-layer data in real-time to verify RF parameters, validate MAC-level communication, troubleshoot interoperability issues, and improve network performance. The analyser features an input DS frequency range of 5 MHz–1.8 GHz (5–200 MHz US), and resolution of 1 MHz. It has up to 7 acquisition cards of 200-MHz bandwidth each (5 DS, 1 US and 1 additional US or DS).

Contained in a single, 19in (48 cm), 4U rack for minimal footprint (60 lbs/27 kg), the analyser has many channel-filtering and display features like placement, burst, constellation, and spectrum
