Anritsu MS27103A Remote Spectrum Monitor – The perfect tool for cellular spectrum assurance
Spectrum Assurance
Interference mitigation of cellular networks is a top priority for optimizing networks and maximizing revenue for cellular network operators. The MS27103A provides spectrum assurance with all applications being accessed and controlled remotely. Interference and unusual signal activity can be monitored and recorded, threshold alarms can be set and signals of interest geo-located. With the Anritsu spectrum monitoring system, your spectrum investment is protected.
Signal Detection and Mitigation
The MS27103A allows users to monitor spectrum for interference signals which can cause slow data rates and dropped calls. Using algorithms such as power of arrival and time distance of arrival, interference signals can be accurately positioned.

Communicating with Remote Spectrum Monitors
Integrated Web Server
Using an internet browser (Chrome and FireFox are supported), a user from anywhere in the world can log in to the spectrum monitor and control any of its features. This includes such parameters as frequency setting, RBW/VBW control, reference level configuration and many other settings relevant to the user’s spectrum monitoring application. At the same time, trace data, spectrograms and other measurements can be viewed inside the browser window.
SCPI Programming
Users can also write their own monitoring program using available SCPI commands. Anritsu provides a user manual listing each SCPI command, a description of the commands and the correct syntax required for each command. Additionally, each individual pair of IQ data output by the monitors is time-stamped using high precision GPS signals. This enables the use of IQ data for Time Distance of Arrival (TDOA) applications for geo-locating signal positions.
VisionTM Application Software
Vision works with the monitoring hardware to automate the process of collecting measurement data, providing useful information about network heath and use of the spectrum. Two components of Vision, Vision Monitor and Vision Locate, are responsible for monitoring and locating interference signals. Vision Monitor automatically records spectrum data, maintains a searchable spectrum history database, enables alarm functions for unusual signal activity, automatically sends email alerts and provides a set of tools for managing the spectrum monitoring system. Vision Locate provides the capability to geo-locate interference or illegal/unlicensed signals.
SpectraVisionTM Application Software
For more detailed analysis of satellite signal quality, SpectraVision software is available to demodulate signals using the DVB-S1, DVB-S2 and IESS standards. Parameters such as C/N, MER, EVM and modulation/coding schemes are presented. Alarms can be triggered based on such parameters as EVM or MER when values fall below a certain user-defined threshold.
Key Benefits of Remote Spectrum Monitoring
• Automation and scalability
• Using Vision software or your own applications, users can identify patterns of interference, record a spectrum history and locate the sources of problem signals
• SpectraVision software allows users to perform signal analysis for satellite and other signal types
• New features and options can be added remotely, no site visits required
Key Applications
• Network interference monitoring
• Geo-location of interference signals
• Maintain spectrum history and generate reports
• Set power threshold levels to automatically generate alarms
