SECTION III. OPERATION
Option H40 is designed to provide an 8662A with very low 640 MHz-output phase noise. To
preserve this performance, the user should isolate the 8662A from sources of vibration and
acoustic noise an much as possible. These disturbances may cause microphonic spurious
responses on the output. One possible way to minimize external vibration coupled to the 8662A is
to place the instrument on a foam pad.
Also,
note that the 8662A itself produces power-line related spurious signals, as well as
fan-generated microphonic spurious signals on its output signal. These spurious signals are not
included in Option H40 specifications.
SECTION IV. PERFORMANCE TESTS
On pages 4-25a through
4-25f,
replace all references to "(Option 003 only)" with "(Option
003/H40 only)".
On page 4-25a, in 4-12, ABSOLUTE SSB PHASE NOISE ON REAR PANEL 640 MHZ
OUTPUT (Option 003/H40 only), replace the table under SPECIFICATION with the table at the
top of page 3 of this Insert.
