LeCroy measures CMRR with a fixture that connects
the probe tip ground to the signal source ground. This
method is necessary to obtain a reproducible CMRR
measurement.

Often, users leave the probe tip ungrounded when
measuring high frequency signals. Not grounding the
probe tip can actually improve CMRR by allowing
some of the common mode signal to be impressed
across the entire length of the probe cable instead of
from probe tip to probe ground. The CMRR
improvement obtained without grounding the probe tip
depends on proximity to probe cable ground, and is
therefore nonreproducible.

LeCroy has chosen to use a reproducible method of
measurement, rather than obtain a more optimistic
measurement.
