OFFSET
DELA

Species
the
one-way electrical
delay from
the measurement
(reference) plane
to the
standard in
seconds (s).
(In a
transmission standard,
oset delay
is the
delay from
plane to
plane
.)
Delay
can
be calculated
from the
precise physical
length of
the oset,
the permittivity
constant
of
the
medium,
and
the
speed
of light.
