Software Enables GPS Rx Verification

The N7609B Signal Studio for Global Navigation Satellite Systems software from Agilent Technologies works with the firm's PXB baseband generator and channel emulator platform to form a 12-satellite, 24-channel signal simulator for Global Positioning System (GPS) receiver verification. The software allows engineers to easily create real-time multisatellite GPS signals and perform the tests required for full GPS receiver verification. Tests can be run with either a stationary or moving GPS receiver with up to 24 channels of line-of-sight and multipath satellite signals. Additional impairments, such as ionospheric and tropospheric attenuation, can be included. The N7609B software runs on the N5106A PXB Baseband Generator and Channel Emulator platform with an E4438C ESG or N5182A MXG Vector Signal Generator for RF upconversion. The N7609B software with PXB/MXG can be combined with Agilent's 8960 Wireless Communications Test Set in the GS-9000 A-GPS Design Verification Test System for complete A-GPS preconformance test coverage.
