This sets a `tolerance window` on the monitored Eb/No. The AUPC will only attempt to restore the monitored Eb/No to the target Eb/No when the monitored Eb/No moves outside the tolerance window. This It is to prevent the AUPC continuously adjusting the power to compensate for minor normal Eb/No variations.

When the monitored Eb/No moves outside the tolerance window the AUPC will attempt to restore it back to the target value (ie not just back inside the tolerance window again).
