MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The offsetScaledLogVariance is scaled, offset
representation of an estimate of the PTP variance. The
PTP variance characterizes the precision and frequency
stability of the ClockMaster. The PTP variance is the
square of PTPDEV (see B.1.3.2). The value shall be
selected as follows:
a) offsetScaledLogVariance is set to the value that
reflects the combination of the LocalClock and
ClockSource entities; else
b) if the value that reflects these entities is not
specified or not known, offsetScaledLogVariance is
set to 16640 (410016). This value corresponds to the
value of PTPDEV for observation interval equal to the
default Sync message transmission interval (i.e.,
observation interval of 0.125 s, see 11.5.2.3 and
B.1.3.2).
A value of -37268 indicates value is too large to be
represented or has not been computed.
