RPM3000

COMMUNICATIONS TEST & MEASUREMENT SOLUTIONS PathTrak™ RPM3000 Monitoring Module for PathTrak Return Monitoring System Key Features • Quickly and easily integrates with current PathTrak systems, including HCU400/1500, HSM-1000 and RPM1000/2000 via field-installable firmware and PathTrak server, client and WebView server software upgrades • Measures transient noise as short as 1 µs • Optimized QAM and spectrum analyzer on every port • 500 kHz to 85 MHz frequency range—compatible with DOCSIS® V3.0 • 50 dB dynamic range • Wide variety of resolution bandwidth (RBW) and video bandwidth (VBW) filters QAM/QPSK level, MER, and constellation measurements on individual carriers • Carrier-to-Composite Noise—in-service ingress under the carrier on QPSK or QAM carriers Applications The RPM3000 module is an eight-port, high-speed return path quadrature amplitude modulation (QAM) and spectrum analyzer optimized for the QAM and ingress analysis and monitoring functions of the PathTrak Performance Monitoring System. Each of the eight ports is an independent and isolated test port. The RPM3000 module switches automatically between the eight ports and individually measures both QAM and spectrum performance on each. The measurement settings and functions of the RPM3000 consist of all typical spectrum analyzer settings such as resolution bandwidth, video bandwidth, dwell time, span, marker control, maximum hold, minimum hold, peak search, and zero span. The RPM3000 provides flexibility to adjust these parameters in monitoring plans, or provide interactive analysis according to individual preferences. Fast Scanning—Catches the Most Transient Noise and Ingress The RPM3000 consists of a single QAM/spectrum analyzer measurement receiver with eight individual input ports that are switched into the receiver. The overall measurement speed across ports is optimized through use of an integral highspeed switch, unique measurement algorithms, digital receiver technology, and dual digital signal processing (DSP) hardware architecture. In addition, the RPM3000 is designed with a detector for measuring very fast transient noise, ingress, and bursty signals. The RPM3000 can reliably detect and measure bursts of noise as short as 1 µs. • Scans 50% faster than RPM2000 • Provides DOCSIS-compliant measurements for live troubleshooting and node certification reports • Provides Web-based access to live and historical measurements on every node • Offers highly customizable monitoring plans on every node • Measurements accessible through the JDSU NetComplete Service Assurance Solutions and through third-party or in-house operation support systems (OSS) with open data formats WEBSITE : www.jdsu.com/test RPM3000 MODULE Flexible Measurement Plans to Adapt to User Preferences Users have ultimate flexibility in programming the RPM3000 for realtime troubleshooting and monitoring. The measurement parameters of individual ports can vary, which allows the user to program each of the eight ports on a single RPM3000 with a different measurement plan. In addition, within an individual port, the measurement parameters can be varied by frequency allowing different spans of the return spectrum to be scanned with different resolutions, or certain spans of the spectrum to be skipped altogether. Expands and Scales with No Degradation in Performance As part of the PathTrak Performance Monitoring System, the RPM3000 monitoring modules are virtual memory extension (VME)-based cards that mount into a modular headend controller unit (HCU) control chassis (HCU400 or HCU1500). Thus, a monitoring system can be designed to serve the existing number of test points today, and then can be expanded easily by adding additional RPM3000 modules. Furthermore, because each RPM3000 module is an independent QAM and spectrum analyzer receiver, adding modules to accommodate more test points does not adversely affect the overall system speed or performance.
