The iSAFT SpaceWire Front-End is a SpaceWire data interface with advanced asynchronous transmission and traffic generation capabilities that simulates SpaceWire devices or Instruments, enabling S/C integration tests before the availability of Flight Models.

It also constitutes a high performing, SpaceWire Link Analyser with modern network traffic capture, recording and analysis capabilities for the validation of satellite/spacecraft flight devices or ground testbed  devices implementing the SpaceWire protocol family.

It is provided as a rackmount system with 4 – 16 SpaceWire ports with advanced traffic generation and asynchronous transmission capabilities. It is capable of transmitting/receiving data packets over multiple SpaceWire links, time stamping received packets, and capturing transmitted/received traffic to a powerful Protocol Analyser. It is based on the iSAFT graphical tool chain, for the configuration & management of the simulation & recording (locally or remotely). It is a powerful device for the validation of on-board data networks at early stages, minimizing costs and schedule. It can be part of EGSE Data Front Ends and implements the core functionality of an EGSE controller.

As a Link Analyser (passive monitoring), it is capable of capturing data packets on multiple SpaceWire links, time stamping, recording, and delivering them to a powerful Protocol Analyzer for further processing & analysis. Operating on a multi-Gbytes powerful HW platform, the SW environment is based on the iSAFT graphical tool chain, thus allowing the management, filtering & searching of the recordings. It is used for troubleshooting and problem solving at various development stages, minimizing the impact on cost and schedule.

The iSAFT SpaceWire Front-End / Link Analyser is offered in the following form factors:

Rackmount System – 1U	Rackmount System – 2U	Rackmount System – 3U
