The STAR-Dundee SpaceWire Physical Layer Tester (SPLT) features hardware which enables it to perform tests across the SpaceWire standard from the physical and signal layer right up to the network and protocol layer. By incorporating components from other established STAR-Dundee products, including the Link Analyser Mk2 and Conformance Tester, the SPLT is the perfect tool that can be used throughout all stages of SpaceWire development from planning requirements through to production testing of flight components. The SPLT transmits SpaceWire LVDS signals at programmable swing and common mode voltages, slew, skew and bit speeds to test the capability of the Unit Under Tests (UUT) to maintain a SpW link without disconnecting. To do this, the SPLT can be configured as a SpaceWire interface on a SpW router. Alternatively, the SPLT can be configured to be placed in the middle of a SpW link between two SpW ports under test and manipulate the SpW signals in both directions. Software running on a host Personal Computer (PC) is used in conjunction with STAR-Dundee's STAR-System device drivers and software to control the SPLT.
