ment and manual identification information.
1 ·2. SPECIFICATIONS
Operating specifications for the 3585A are listed in Table 1 - 1 . These specifications are the
performance standards or limits against which the instrument is tested . Any changes in
specifications due to manufacturing, design or traceability to the U.S. National Bureau of
Standards are included in Table 1 - 1 of this manual. Specifications listed in this manual
supersede all previous specifications for the Model 3585A.
1 ·3. INSTRUMENT AND MANUAL IDENTIFICATION
The instrument identification serial number is located on the rear panel. Hewlett-Packard
uses a two-section serial number consisting of a four-digit prefix and a five-digit suffix
separated by a letter designating the country in which the instrument was manufactured. (A
=
U. S.A. ; G
=
West Germany; J
=
Japan; U
=
United Kingdom.) The prefix is the same
for all identical instruments and changes only when a major instrument change is made. The
suffix, however, is assigned sequentially and is unique to each instrument .
This manual applies to instruments with serial numbers indicated on the title page. If
changes have been made in the instrument since this manual was printed, a yellow "Manual
Changes" supplement supplied with the manual will define these changes and explain how
to adapt the manual to the newer instruments . In addition, backdating information con
tained in Section VII adapts the manual to instruments with serial numbers lower than those
listed on the title page.
