Instrument
Specication
Specications
are
the
performance
characteristics
of
the
instrument
that
are
certied.
These
specications
,
listed
in
T
able
C-1,
are
the
performance
standards
or
limits
against
that
the
HP
81554SM
can
be
tested.
Appendix
C
also
lists
some
supplemental
characteristics
of
the
HP
81554SM
and
should
be
considered
as
additional
information.
Any
changes
in
the
specications
due
to
manufacturing
changes
,
design,
or
traceability
to
the
National
Bureau
of
Standards
will
be
covered
in
a
manual
change
supplement
or
revised
manual.
The
specications
listed
in
such
a
change
supercede
any
previously
published.
