Agilent/Keysight 37907A

The Keysight 37907A Signaling Advisor is a mainframe instrument engineered for real-time analysis and troubleshooting of signaling networks across SS7, Cellular, PCS, GSM, GPRS, UMTS, and cdma2000 architectures. It performs non-intrusive monitoring and detailed traffic analysis with dedicated processors for data acquisition and user interface optimization. The system supports up to 32 duplex signaling links at 64 kb/s per erlang, expandable to 16 duplex physical bearers with optional undercradles.

Two LIM slots accommodate Link Interface Modules for protocol flexibility and future technology integration.
