Preface
PREF CE
This manual is designed to present the information required by the user to effectively operate
and maintain the 5335A Universal Counter.
It is divided into sections each relating to a specific topic. As much aspossible the sections are
self-contained. It isthe intention of this manual to allow for the quick location of desired infor-
mation while still providing the overall depth of detail required. Some sections provide the
learning and working information and will be used frequently. Other sections are dedicated to
general and introductory types of information and are intended to be used only for reference.
Where applicable photos illustrations and diagrams foldout allowing the user accessto related
information throughout the manual.
In limiting the depth of coverage in this manual a certain amount of previous knowledge on
the part of the reader must be assumed. A variety of additional related documentation is avail-
able. These materials address in depth the specific areas of interest and should be used
whenever necessary to supplement this manual. Users unfamiliar with HP IB or Logic
Symbology for example may want to refer to the 5335ADocumentation Map to find additional
sources of information.

General Information
SECTION I
GENER L INFORM TION
1 1. INTRODUCTION
1-2. This Operating and Service Manual contains
the information required to install, operate, test, ad-
just, and service the Hewlett-Packard Model 5335A
Universal Frequency Counter. Figure 1-1 shows two
examples of the 5335A counter. One instrument isa
standard unit with no options. The other instrument
has the optional digital voltmeter (Option 20), the
third input amplifier or C channel (Option 30),and
the programmable input amplifiers (Option 40).
1 3. MANUAL SUMMARY
1-4. This manual isdivided into eight sections, each
covering a particular topic for the operation and
. service of the HP5335A.The topics by section number
are:
SECTION I GENERAL INFORMATION. Provides the
instrument specifications, instru ment identification,
description of options, accessoriesand recommended
test equipment.
SECTION II INSTALLATION. Provides information
about initial inspection, preparation for use, storage
and shipment, field installation of options, and HP-IB
intercon nections.
SECTION III OPERATION AND PROGRAMMING.
Provides information about operating characteristics,
panel features, local and remote operating instruc-
tions, operator's maintenance, and programming. The
operation of Options 020,030and040isincluded in this
section.
SECTION IV OPERATIONAL VERIFICATION. Provides
abbreviated procedures for operational verification
which give the operator a high degree of confidence
that the 5335Ais operating properly.
SECTIONV, ADJUSTMENTS.Provides the procedures
required to properly maintain the instrument oper-
ating characteristics within specifications.
SECTION VI REPLACEABLE PARTS. Provides ordering
information for all replaceable parts and assemblies
within the instrument.
SECTION VII MANUAL CHANGES. This section con-
tains manual change information which effectively
backdates the technical areasof the manual to apply
to older instruments.
SECTION VIII SERVICE. This section provides the
instrument theory of operation, troubleshooting in-
formation, repair techniques, and schematic diagrams.
1 5. SPECIFICATIONS
1-6. The instrument specifications are listed in Table
1-1. These specifications are the performance stan-
dards or limits against which the instrument may be
tested.
1 7. SAFETY CONSIDERATIONS
1-8. The 5335A Universal Counter is a Safety ClassI
instrument (provided with aprotective earth terminal),
designed according to international safety standards.
This operating and service manual contains informa-
tion, cautions, and warnings which must be followed
by the user to ensure safe operation and keep the
instrument in safe condition.
1 9. INSTRUMENT IDENTIFICATION
1-10. Hewlett-Packard instruments have a two-
