8662A Option

Since
the
8662A Option
H30 is
factory-selected
to
meet more stringent specifications, repair,
replacement, and/or adjustment
of
critical parts
and
assemblies could degrade performance back
to
standard
specifications. Under these conditions, Hewlett-Packard's warranty obligation would
be to the
standard
specifications,
not to the
Option
H30
specifications.
For
these reasons, Hewlett-Packard recommends that
the
8662A Option H30
be
returned
to the
factory
for
any repairs
or
adjustments which may affect phase noise
performance.
SECTION IV. PERFORMANCE TESTS
On page 4-15
and
4-17,
in
Sections 4-8
and
4-9, SSB PHASE NOISE TEST
and
SSB PHASE NOISE
TEST (OPTIONAL), replace
the
sections titled Residual SSB Phase Noise
in
1
Hz
Bandwidth, with
the top
portion
of
Table
1-1 on
page
1
of
this Insert.
On pages 4-25a through 4-25f (See
the
yellow Manual Change sheets shipped with
the
unit), replace
all
references
to
"(Option 003 only)" with "(Option 003/H30 only)".
On page 4-25a,
in
Section 4-12, ABSOLUTE SSB PHASE NOISE ON REAR PANEL 640 MHZ
OUTPUT (Option 003/H30 only), replace
the
SPECIFICATION table with
the
lower portion
of
Table
1-1 on
page
1
of
this Insert.
On page
4-25f, in
Section 4-12,
in the
table under Limit (dBc/Hz), replace
"-145"
with "-147".
SECTION V. ADJUSTMENTS
Certain adjustments, such
as
5-8,
the 40
MHz CRYSTAL FILTER ADJUSTMENT, directly affect
the
phase noise
of
the 8662A. Other adjustments, such
as
5-9, 5-10,
and
5-11,
can
indirectly affect
the
phase noise
of the main RF Output. Therefore, use caution when making
any
adjustments
on
Option H30,
and
verify phase
noise performance after making
any
such adjustments. Refer
to the
first paragraph
at the top of
page
2 of
this
Insert
for
further information.
SECTION
VI.
REPLACEABLE PARTS
There
are no
changes
in
this section.
SECTION VIII. SERVICE
Before proceeding with repair, replacement,
or
adjustment
of
parts
or
assemblies
of
Option H30, refer
to
the first paragraph
at the top of
page
2 of
this Insert.
