Positive Train Control (PTC) is an advanced communications system to minimize train accidents by automatically controlling train activity. This includes real-time monitoring of static and dynamic conditions that require the train to slow or stop.
Clifton Weiss & Associates, Inc. (CWA) was retained as professional consulting engineers to conduct a 3-year study of interfering RF signals on an actively operating Northeast commuter railway.
The Case Study talks about and discusses the challenges and solutions.

The MS27103A provides 12 RF Input ports as a standard configuration (24 RF Input ports are available with Option 424). This model is typically used with three or six sector BTS architectures, with multiple carriers per sector. A high speed switch is placed in the monitor to provide measurement capability for each RF input. A greater than 30 dB isolation is provided between each RF Input port to assure the integrity of the measurement.

Vision software is also provided as an option for all spectrum monitor models. 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. Vision is composed of two components responsible for monitoring and locating interference signals, called Vision Monitor (option 400) and Vision Locate (option 401). Vision Monitor automatically records spectrum data, maintains a searchable spectrum history database, enables alarm functions for unusual signal activity 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. To properly locate signal positions, three or more monitors must be used.

To communicate with the MS2710xA Remote Spectrum Monitor or to change its IP configuration, a PC must be correctly set up to communicate with the instrument via a direct connection using a static IP. The sections in this guide explain using:
– a Windows PC to directly communicate with the Anritsu spectrum monitor
– SCPI commands for configuring the Ethernet and DNS settings
– the Anritsu Windows network discovery tool to find the instrument IP address

This documentation provides a description of the Anritsu’s Remote Spectrum Monitor (RSM) and Vision Software API’s. It describes the graphical user interface, provides a how-to chapter to set up measurements, discusses API programing, and covers a lists of API programming commands. API's are presented both for control of Anritsu's RSM hardware product line (MS2710XA) as well as for Vision software. Most features in Vision are paid options. In order for these options to work, the RSM hardware must have these options
enabled. Please see the Vision software Product Brochure and User Guide for option information.
The MS27103A is ideal for satellite operators and broadcasters who need to rely on clear
communication channels to ensure optimal
performance. A typical earth station will consist of many satellite dishes, all of which need to be monitored in real time. The MS27103A multiport remote spectrum monitor enables the spectrum of each satellite uplink or downlink to be monitored for spectral purity and the presence of interferers. Alarms can be automatically triggered on detection of unwanted interferers that would degrade the signal integrity.
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.
SpectraVision is a suite of software options and tools used with Anritsu’s MS2710XA product line of spectrum
monitors. SpectraVision is a highly modular software system covering the entire frequency range of Anritsu’s
Remote Spectrum Monitors. Various features incorporated into the software allow users to quickly perform
automated analyses of the frequency spectrum, record measurements and generate optional reports detailing
signal quality and performance characteristics.
The Vision™ software platform works with Anritsu’s spectrum monitoring hardware to automate the process of collecting measurement data, providing useful information about network health and use of the spectrum. Using multiple hardware probes covering a wide geographical area, Vision presents a comprehensive picture of spectral activity to assist users in monitoring the spectrum for unusual activity. Figure 2 shows a typical signal monitoring system with Anritsu spectrum monitors positioned for maximum coverage.
Capable of sweeping at rates up to 24 GHz/s, the MS27103A allows capture of many types of signals. This includes periodic or transient transmissions as well as short “bursty” signals. Also featured is a high dynamic range, high sensitivity and low spurious signals. This enables the MS27103A to reliably distinguish between low-level signals being observed and those signals generated by the monitor itself.
This user guide describes the software functions and working instructions of the SpectraVision software. Based
on an efficient, proven client-server principle, the software architecture allows for shared devices (instruments)
and remote services. SpectraVision software works only with Anritsu's product line of remote Spectrum
Monitors (Models MS27100A, MS27101A, MS27102A and MS27103A).
Time Difference of Arrival (TDOA) is a technique for geo-locating RF sources. It requires three or more
remote receivers (probes) capable of detecting the signal of interest. Each probe is synchronized in time to
capture corresponding I/Q data blocks. Software shifts the time signature of each I/Q data set to find the
difference in the arrival time at each probe. This gives the difference in the distance of the source from each
set of probes. Using several probes provides a set of curved lines that indicate solutions to the distance
equations. The actual RF source sits at the intersection of these lines.
TDOA can provide a very accurate location estimate (< 100 m) in a short period of time. To successfully use
TDOA it is essential to understand the type of signals that can be used, how the results depend on the
geometry of the measurement (probe and source
locations), what the sources of uncertainty are and
how to mitigate them, and how to know if the
answer is meaningful.
