Since the 8662A Option HI8 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 HI8 specifications. For these reasons, Hewlett-Packard
recommends that the 8662A Option HI8 be returned to the factory for any repairs or adjustments
which may affect phase noise performance.

SECTION IV, PERFORMANCE TESTS
On page 4-15, in 4-8, the SSB PHASE NOISE TEST, in the SPECIFICATION table, replace
the section titled Residual SSB Phase Noise in
1
Hz Bandwidth with the partial Table 1-1 on page
1 of this Insert. Also, add the following under DESCRIPTION: "The following test procedure
may be used as a general performance check of the phase noise of Option HI8. However, since
Option HI8 is defined as being tested on an HP 3047A Spectrum Analyzer System, only this
System (and suitable low-noise local oscillators) should be used to verify the performance of
Option H18."
On page 4-17, in 4-9, SSB PHASE NOISE TEST (OPTIONAL), in the SPECIFICATION
table, replace the section titled Residual SSB Phase Noise in
1
Hz Bandwidth with the partial
Table 1-1 on page
1
of
this
Insert. Also, add the following under DESCRIPTION: "The following
test procedure may be used as a general performance check of the phase noise of Option HI8.
However, since Option HI8 is defined as being tested on an HP 3047A Spectrum Analyzer
System, only this System (and suitable low-noise local oscillators) should be used to verify the
performance of Option HI 8."
