Compliance with spectrum regulations is often enforced by spectrum monitoring. Figure 1 shows the MS27102A deployed to monitor Positive Train Control (PTC) frequencies. PTC is being deployed worldwide to provide automated signaling for train control. The MS27103A can also be used inside the train to insure wireless integrity.

With monitors potentially being deployed hundreds or thousands of kilometers from the control center, it is imperative that each probe remain operational under all types of conditions. The MS27102A is designed for robust field deployments, with capabilities for remote power cycling, automated system recovery protocols and firmware updates “pushed”...
MS27102A Remote Spectrum Monitor Integrated Web Server The MS27102A features an 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.

MS27102A Remote Spectrum Monitor Accidental Interference A wide variety of accidental interference can be seen in the spectrum. A common problem is cable TV leakage. This type of leakage exists both from cable signals leaking into the outside environment as well as from external signals leaking into the cable system.
