What the GSS6450 does

SPIRENT의 GSS6450 Record & Playback System(RPS) 는 쉽고 빠르게 GNSS 및 기타 RF 신호를 차후 사용을 위해 저장할 수 있는 기능을 제공합니다.

GSS6450 RPS는 실제 RF 환경기반의 신호를 저장하며 해당 저장된 RF 신호를 차후에 Playback 할 수 있으며, 다중 경로, 페이딩, 모호화 및 간섭과 같은 전파 효과를 충실하게 재현하여 실제 조건에서 GNSS 칩셋, 수신기 및 시스템 테스트를 지원하고 있습니다.

여러 주파수 대역을 동시에 기록할 수 있는 GSS6450의 유연성은 RPS를 사용하여 무선, 셀룰러, 자동차, 내비게이션, 항공 우주, 방위 및 측량 애플리케이션에서 다중 GNSS 칩셋과 장치를 테스트하는 데 사용할 수 있음을 의미합니다.

GSS6450 RF RPS에는 3 개의 RF I/O 포트가 포함되어 있습니다. RF1은 GNSS 신호의 기록 및 재생을 위해 필터링을 최적화했으며 RF2 및 RF3는 각각 셀룰러 및 광대역 신호를 처리하기 위해 더 넓은 대역폭을 제공합니다.

추가적으로 간섭 및 Jamming 테스트를 위해 내장된 스펙트럼 분석 소프트웨어를 사용할 수 있습니다.

l  Scripts allow inclusion in automatic test routines

l  GSS6425 Compatibility mode to play back 2bit files recorded on a GSS6425

l  Output of raw I/Q data on Aux port (Two most significant bits of each channel).

CANbus

l  Two in built-High-Speed CAN interfaces which allow CAN bus data to be recorded as synchronous data without the need for an external interface unit.

n  The CAN interface is a passive device which records the signal levels seen on the CAN bus. It does not provide bus acknowledgements etc. When replaying CAN Data onto a CAN bus with other transmitting nodes, the GSS6450 will transmit data even if another node is already transmitting causing corruption of data on the CAN bus. It is not recommended to replay CAN data onto a vehicle or any other CAN Bus in a safety critical application.

l  With the (optional) PCAN Router FD two CAN FD or High-Speed CAN busses can be recorded, and played back, synchronously with the RF data.

n  Input or output CAN messages can be filtered.
