3.15.2 References Probe Setting
The References Probe Setting dialog (see Figure 3.130 on page 202 ) allows you to set the
three reference points defined by the SAS 3.0 specification (Reference 1, Reference 2 and
NoEq), in cases when the default reference points do not result in a clean link.
These settings only need to be applied once for each analyzer as they are saved by the
SAS/SATA Protocol Suite application on the host machine. Connecting to a different host
machine requires reapplying the settings.
