CATV/QAM/ Video Spectrum Analyzer

The AT2500RQ4 (Version 4) is the industry’s most complete spectrum analyzer, combining superior QAM analysis, digital proof-of-performance via the WebRemote option, and the analog capabilities of its Version 3 predecessor.

Today’s broadband network technicians face the challenge of keeping the soon to be “all digital cable plant” operating at peak performance at all times. With its enhanced QAM performance, the Version 4 AT2500RQv allows technicians to quickly perform sophisticated tests and get accurate results at higher MER levels, even on those difficult Annex A QAMs. Designed with PC technology in mind, the Sunrise Telecom AT2500RQ4 is a lightweight, full featured 1.5 GHz spectrum analyzer built to withstand the rigors of field use and to perform equally as well in today’s sophisticated headend environments.

Features

• Superior QAM demodulation capability and excellent BER performance, featuring MER capability up to 43 dB on Annex A
• QAM analysis includes constellation, statistics, group delay, frequency response and impairment analysis for Annex A, B and C signals
• 1.5 GHz high sensitivity spectrum analyzer with built-in automatic filter for increased dynamic range
• Adjustable bandpass filter provides excellent dynamic range
• AT2500 WebRemote offers one–button digital proof of performance as well as many other features, including remote operation and switch control, all via a simple web connection
• Complete set of CATV measurements including CCN, CSO, CTB, ICR, DOM, Hum and carrier frequency
• Built-in auto-filter significantly increases the dynamic range for both digital and analog measurements
• Multiple trace display with detector selection and enhanced markers for added flexibility

Benefits

• Performs all FCC tests without service disruptions. using a gated signal
• Performs SCTE-40 type measurements with one-button testing
• Detects RF signal impairments before they turn into customer complaints
• Integrated analog and digital measurements, both local and remote, in one analyzer
• Isolates difficult-to-locate impairments using enhanced trace detector and marker capabilities
• Characterizes return path for DOCSIS 3.0 advanced services with 64 QAM Upstream demodulator, including simulated “equalizer off” capability (requires CM2xxx or CM3xxx with CM2-USG option)
• Allows you to utilize your web browser to run comprehensive remote testing anytime from anywhere.
