HP E4902B 26.5 GHz Spectrum Monitoring System

Product Summary

Interference threatens the continued growth of radio communications in two ways: in existing installations, capacity is diminished, increasing error rates and disrupting base station operation; and new systems have difficulty finding interference-free bands in which to operate. The HP E4902B spectrum monitoring system can efficiently detect interference and manage frequency assignments for telecommunications service providers, regulatory agencies, civil aviation authorities, and the military. The system is based on an HP spectrum analyzer and includes Microsoft Windows-based software running on a powerful HP Vectra PC. The HP E4902B provides a variety of measurement tools to characterize the RF spectrum, such as multiple-band signal logging, spectral occupancy statistics, and optional demodulation and recording. A set of coordination tools, including task scheduling for around-the-clock, unattended operation and alarms for tracking intermittent signals, can greatly increase productivity. Data can be summarized with over a dozen standard reports, including signal logs, spectral occupancy, carrier analysis, and system and alarm logs. Customized reports can also be created by exporting data to popular spreadsheets and word processors.

Product Features

• PC Windows-based operation for ease of use

• Multiple-band signal logging, both interactive and scheduled

• Spectral occupancy statistics to assess channel usage

• Task scheduling for 24-hour-a-day monitoring

• Alarms to track intermittent signals by recording data only when a signal is present

• Remote operation for monitoring multiple sites from a central controller

• Standard and custom reports for concise summaries of long monitoring sessions
