Safety
Familiarize yourself with the safety symbols marked on the analyzer,
and read the general safety instructions and the symbol definitions
given in Chapter 16 , “Safety and Regulatory Information,” before you
begin the procedures in this chapter.
Test Equipment You Will Need
Refer to Chapter 1 of the calibration guide for your instrument for a list
of recommended equipment for the analyzer adjustments. Any
equipment that meets the critical specifications given in the table can
be substituted for the recommended model.
If a 3335A Synthesizer/Level Generator is not available, see Chapter 1
of the calibration guide for your instrument for alternative
recommended test equipment, accessories, and adapters.
When A 3335A Source Is Not Available
The 3335A Synthesizer Level Generator signal source has become
obsolete because parts used in the manufacture of this instrument are
no longer available from suppliers. To meet the need of our customers,
this service guide has been revised to add new adjustments that do not
use the 3335A Synthesizer Level Generator. This revision includes the
addition of signal sources required to replace the 3335A, changes i to
the test equipment setup illustrations, and changes in the steps
required to execute the adjustments.
Since all of our customers will not need to replace their 3335A
Synthesizer Level Generators immediately, the original adjustments
which use the 3335A signal generator have been retained. The
revisions have been incorporated in this service guide as Chapter 2a ,
“Making Adjustments: If 3335A Source Not Available.”
