Keysight / Agilent 37908A Overview

The GSM / GPRS Signaling Advisor is a software application designed to run on a dedicated mainframe. The resulting instrument isolates the relevant messages faster, making it easy to troubleshoot problem calls. This package supports all of the protocol stacks required for monitoring GSM Phases 1, 2, 2+ including CAMEL and GPRS, as well as basic wireline network signaling. Add any appropriate optional decodes and link interface modules and you''re ready to test across multiple links involving different protocol standards, e.g. at access network interfaces. At the heart of each GSM / GPRS Signaling Advisor, the intuitive graphical user interface makes measuring and understanding results easy, speeding diagnosis of network problems.

A range of link interface modules provide the physical interfacing to network equipment. Each link interface module (LIM) connects to one type of physical interface (eg, E1or T1), providing access to all signaling links on up to four bi-directional bearers. Optional undercradles expand capacity to four LIMS (16 bi-directional bearers), or provide Ethernet connectivity.

The architecture of the software and mainframe makes it easy for you to keep up with changing technologies and data rates, minimizing the need to replace equipment. Simply add a LIM or decode to bring your instrument in line with new needs. High performance and flexibility are designed into the Signaling Advisor mainframe, enabling it to cater for today''s and tomorrow''s applications. Separate processors (with independent memory) handle data acquisition and user interface, allowing optimum performance to be achieved.

EmuLite is an option which allows the Signaling advisor to be upgraded to a fully integrated monitor and emulation solution. EmuLite creates and executes tests faster through use of its graphical message and sequence editors. This allows engineers more time to diagnose signaling problems without the need for programming.
