56 Keysight M8070A Programming Guide2 Recommended Programming TechniquesLink Training ConfigurationLink Training Configuration describes the parameters controlling theLTSSM (Link Training and Status State Machine). In the first release it isonly defined and implemented for PCI Express 3.0. This is done with the node. It is inserted just before the node. The following parameters can beconfigured as attributes.Table 18 Link Training ConfigurationName Possible Values Default Value Description Used for DUTTypeDUT Type AddInCardSystemBoardAddInCard Specifies which role the DUTshould play during linktraining. It can either be anupstream device for testinga downstream port or viceversa.BothLinkEqualizationBypassPresetsOnlyFullBypass Determines whether linkequalization should beperformed. It can either beaborted after phase 1(Bypass) or fully executed. Inthe second case it can bedetermined whether onlypreset or all (that is,individual cursor) requestsshould be accepted.BothLane Number 0 - 15 0 This is the lane numberbeing used.BothLink Number 0 - 255 0 This is the link numberbeing used.Add-in CardStart Preset P0 - P9 P4 This is the preset used bythe BERT’s TX port afterswitching to Gen 3operation and whenoperating as an upstreamdevice.Add-in Card
