Cellular network operators have invested billions of dollars in purchasing rights to use frequency spectrum around the world. This spectrum is necessary to deliver the high data bandwidth demanded by smartphone users to view emails, web pages, and stream audio and video while mobile. In order to maintain a high level of network performance, operators need to continually monitor their spectrum to identify and locate sources of interference. Interference can come from illegal transmitters and from unintended sources, such as intermodulation products. All reduce the network’s data capacity, which results in a reduced user experience. Operators can act quickly to protect their investment and maintain data capacity.

Remote Spectrum Monitor – Model MS27103A

The MS27103A remote spectrum monitor is designed to identify and locate interfering signals. This serves to optimize the user experience, a key goal for network operators. This translates into customer loyalty, reduced customer churn, and superior brand.

Additionally, DAS systems are being deployed extensively around the world to provide high data capacity in dense user environments. These include transport hubs, sports stadiums, and shopping malls. From a single equipment room, multiple feeds pan out to a distributed array of antennas. Monitoring for interference signals on each of these RF feeds is essential to maintain capacity for the DAS system. The MS27103A is the perfect monitoring solution for DAS systems to help maintain overall system performance.

The MS27103A is housed in a rack-mountable enclosure with 12 (or optionally) 24 RF Inputs. An electronic switch is used to address each port. The MS27103A is a full-featured platform for monitoring and recording signals at user-specified frequencies.

Capable of sweep rates up to 24 GHz/s, the MS27103A 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 MS27103A monitor provides the ability for wideband real-time capture of signal activity for subsequent post-processing. IQ captures can be recorded both in block mode or streamed. A “save on event” feature is also provided to capture spectrum measurements only when certain user-settable thresholds are violated. This saves memory space since only signals of interest are captured and recorded.
