Remote Spectrum Monitor MS27103A

The Anritsu MS27103A is a high-performance rack-mounted remote spectrum monitor built for large-scale, multi-input RF surveillance. With 12 or 24 switchable RF inputs, 9 kHz to 6 GHz coverage, and 20 MHz real-time FFT bandwidth, it's ideal for cellular networks, DAS systems, and spectrum assurance applications, enabling operators to detect interference, optimize performance, and protect high-value licensed spectrum assets..

  • Specification

Designed to meet the evolving demands of cellular operators and DAS (Distributed Antenna Systems) monitoring, the MS27103A is a multi-channel remote spectrum analyzer with exceptional RF performance. It helps detect and geo-locate illegal transmitters, intermodulation interference, and spectrum misuse, all of which can drastically impact customer satisfaction and network quality.

Its multi-input switchable architecture allows monitoring across various sectors, antennas, or bands, making it perfect for environments such as stadiums, airports, shopping malls, and transport hubs. With 20 MHz real-time FFT, short burst signals can be captured accurately. The “save on event” function conserves storage by only recording critical threshold violations.

Users can interact with the MS27103A using:

  • An integrated browser-based GUI

  • SCPI commands for custom automation

  • Vision Monitor and Vision Locate software, enabling data logging, alarm systems, and real-time geo-location using TDOA (Time Distance of Arrival).

By combining IQ capture, interference hunting, and real-time visualization in a compact, rack-mounted format, the MS27103A helps operators optimize performance, ensure service availability, and protect billion-dollar spectrum investments.
