The Anritsu MS27103A is a multiple RF input spectrum monitor ideal for measuring signals from multiple antennas. The solution provides 12 RF input ports asa standard configuration and is typically used with a three-sector BTS cellular architecture with multiple carriers per sector. A high-speed switch is placed inthe monitor to provide measurement capability for each RF input. This electronic switch can move from port to port in approximately 300 nS. A greater than30 dB isolation is provided between each RF input port to assure the integrity of the measurement. Option 424 allows the MS27103A to be upgraded to 24 RF input ports.

With monitors potentially being deployed hundreds or thousands of kilometers from the control center, it is essential that each one remains operationalunder all types of conditions. The MS27103A is designed for robust field deployments with capabilities for remote power cycling, automated system recoveryprotocols, and firmware updates “pushed” to the monitor remotely.

Using three or more probes, Anritsu’s optional Vision™ software can be used to position an interferer signal or illegal broadcast. Additionally, IQmeasurements are time-stamped using the probe’s GPS receiver. This enables the user to employ their own software using Time Difference of Arrival (TDOA)capabilities to find interferers, given each monitor IQ measurement is precisely time stamped.
