Description

GS-9000

The GS-9000 is a scalable test system built on the 8960 wireless communications test set for testing Assisted GPS (A-GPS) capabilities in mobile devices and chipsets – ensuring A-GPS devices operate as expected in cellular networks without interfering with existing network operation. The GS-9000 family of test systems includes two design verification solutions, one for bench top functional test and another for pre-conformance test. Both test systems are based on test cases defined in 51.010 and 34.171.

The test system includes both hardware and software for testing mobile device A-GPS capabilities in a conducted environment. The hardware includes an 8960 test set with a lab application to emulate the base station and an E4438C ESG Vector Signal Generator to emulate GPS satellites. The GS-9000 Lite compact functional test system provides assistance data, protocol message encoding and decoding, and position location calculations. The GS-9000 standard design verification system performs pre-conformance test including all the tests of the Lite system with additional GPS scenario generation support, including multi-path fading with the Agilent N5106A PXB baseband generator. The system is also designed for optional SUPL server support.

Software includes pre-defined tests that conform to individual technology standards, which can be easily configured or modified when used in the design verification environment. It includes standardized GPS scenarios as well as some customization options in order to make it easy for wireless R&D engineers to more accurately emulate A-GPS usage on a real network.
