Anritsu Remote Spectrum Monitor MS27102A

The perfect tool for government regulators

Spectrum Monitoring

The Remote Spectrum Monitor MS27102A is part of a spectrum monitoring system used to identify and measure spectrum usage and to locate and remove illegal or unlicensed interference signals. This is key in keeping critical communication channels such as transport, broadcasting, public safety, and utilities free of impediments and distortion. Regulating the use of radio transmissions and mitigating interference in the spectrum has become a high priority with government regulators.

Spectrum Occupancy

Spectrum monitoring is also used to characterize spectrum occupancy. Government regulators and operators are often interested in determining the usage rate for various frequency bands. Monitoring these frequencies provides the information needed to optimize spectrum for maximum utilization. Spectrum can be re-purposed for other applications or multiplexed with other signals using cognitive radio techniques.

Continuous. Fast. Reliable.

The Remote Spectrum Monitor MS27102A is designed for outdoor environments where probes are positioned in a permanent or semi-permanent location for radio surveillance and monitoring. Government regulators often

use outdoor monitors for enforcing spectrum policies. Capable of sweep rates up to 24 GHz/s, the Remote Spectrum Monitor MS27102A allows for the capture of many types of signals. This includes periodic or transient transmissions as well as short “bursty” signals. The 20 MHz instantaneous FFT bandwidth available on the Remote Spectrum Monitor MS27102A provides the ability for wideband, real-time captures of signal activity for subsequent post-processing. IQ captures can be recorded both in block mode or streamed.

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, resolution bandwidth/video bandwidth (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 Difference of Arrival (TDOA) applications for geo-locating signal positions.

Vision 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.
