Engineers can directly compare transformer-based isolation against capacitor isolation, observe common-mode noise suppression behaviour, and evaluate EMC and emissions performance.<\/p>\n<p>Arrow provides this tool as a reference schematic solution for new designs which also allows designers to measure network stability in both point-to-point and multidrop 10BASE-T1S configurations, validating network stability and SPE channel performance before a final product design is finalized.<\/p>\n<p>Advanced technical support and customization services are available from Arrow\u2019s engineering solutions center (ESC).<\/p>\n<p>The 10BASE-T1S REF_SPE_T1S reference design is available now through Arrow.
