Press Release Summary:
E7333A DOCSIS Protocol Analyzer enables functional analysis of upstream and downstream protocols by acquiring signals and decoding media access control messages within wide RF dynamic range. It offers up to 16 MB of downstream and 8 MB of upstream acquisition memory. Flexible trigger generation can provide analog triggering signals for physical layer measurement instrumentation. E7333A is controlled with PC and supports DOCSIS 1.0 and 1.1 specifications.
Original Press Release:
Agilent Technologies' New DOCSIS Protocol Analyzer Speeds Development of New Cable TV Systems
DPA Analyzes Both Upstream and Downstream DOCSIS signals
PALO ALTO, Calif., June 11, 2002 -- Agilent Technologies Inc. (NYSE: A) today introduced a commercially available DOCSIS Protocol Analyzer (DPA) that enables functional analysis of both upstream and downstream data-over-cable service interface specification (DOCSIS) signals. The analyzer provides equipment manufacturers and service providers with unprecedented visibility into DOCSIS protocol implementations, speeding
and simplifying development, interoperability testing and certification of equipment and services for delivering high-speed Internet and voice services over cable TV systems.
The Agilent E7333A DOCSIS Protocol Analyzer analyzes the upstream and downstream protocols by acquiring the signals and decoding media access control (MAC) messages within a wide RF dynamic range. The new product also provides a highly versatile triggering subsystem for physical layer measurements, and has applications in R&D testing, conformance testing, manufacturing, and system troubleshooting and monitoring.
The E7333A currently supports DOCSIS 1.0 and 1.1 specifications and is expected to have an option for supporting EURO DOCSIS in the future. It offers up to 16 MB of downstream and 8 MB of upstream acquisition memory. Data flowing into these memories can be filtered by packet identification (PID) in the downstream or by interval usage code (IUC) or service identification (SID) in the upstream. Flexible trigger generation can provide analog triggering signals for physical layer measurement instrumentation such as vector signal analyzers and spectrum analyzers. Engineers can configure these analog triggers to
be coincident with specific IUC pre- and post-burst events, and monitor two upstream IUC selective physical layer measurements (SNR, time and frequency offset).
"The E7333A provides advanced protocol and physical layer testing for DOCSIS cable modems and CMTS systems," said Peter Johnson, DOCSIS business manager for Agilent's Worldwide Custom Solutions Operation. "Engineers can now perform efficient and complete investigations using both the physical layer tools and the MAC layer analysis capabilities built into the second-generation DPA."
The E7333A is controlled with a PC and will operate in the Agilent E1371A/B DOCSIS Design Verification Test System as a direct replacement for the first-generation DOCSIS Downstream Protocol Analyzer or with the PC alone. When used with the PC alone, optional software products to perform MAC and PHY-MAC conformance testing can be utilized to perform the following analysis:
- downstream frame analysis on both the MPEG and MAC frames, including MAC message decoding with search capabilities on SYNC, MAP, UCD, RNGRSP, REGRSP and UCCREQ messages;
- upstream burst analysis with message decoding and search capabilities on RNGREQ, REGREQ and packet messages;
- downstream MAC Timing analysis for Sync jitter and errors;
- DOCSIS 1.1 MAC and MPEG protocol decodes and error checking; and
- synchronized upstream and downstream timing analysis.
