Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

SECTION I
General Information
1-1. Introduction
This service manual explains how to test, adjust,
and service the Hewlett-Packard 16500A/16501A
Logic Analysis System. This manual is divided
into six sections as follows:
I - General Information
II - Installation
III - Performance Tests
IV - Adjustments
V - Replaceable Parts
VI- Service
The General Information Section includes a
description of the HP 16500A/16501A, its
specifications, options, available accessories, and
recommended test equipment for maintaining the
instrument.
Information for operating, programming, and
interfacing with the HP 16500A/16501A is
contained in the Operating and Programming
manual set supplied with each instrument.
Shipped with this manual are service manuals for
each module ordered with the HP
16500A/16501A. To complete the service
documentation for your system, unpack the
module service manuals and place them in the
3-ring binder of this manual.
1-2. Instruments Covered by This
Manual
The instrument serial number is on the rear panel
of the instrument. Hewlett-Packard uses a
two-part serial number consisting of a four-digit
prefix and a five-digit suffix separated by a letter
(for example, 0000A00000). The prefix is the
same for all identical instruments and the suffix is
different for each instrument. Prefix changes are
for parts compatibility and for instrument tracking.
The only time the manual will be updated to reflect
a new prefix is for parts compatibility. This manual
applies directly to instruments with the serial prefix
shown on the title page.

1-3. Safety Considerations
Review the instrument and manual for safety
markings and instructions before operating it.
Specific warnings, cautions, and instructions are
placed wherever applicable throughout the
manual. These precautions must be observed
during all phases of operation, service, and repair
of the instrument. Failure to comply with these
precautions or with specific warnings elsewhere in
this manual violates safety standards of design,
manufacture, and intended use of this instrument.
Hewlett-Packard assumes no liability for the
customer’s failure to comply with these safety
requirements.
1-4. Product Description
The HP 16500A is the mainframe of the HP Logic
Analysis System. The HP 16501A is an
expansion frame of the HP Logic Analysis System.
The HP 16500A/16501A is of modular structure
using plug-in cards with a wide range of data
acquisition and stimulus capabilities.
This allows the user to configure the system with
