About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
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

SECTION II
Installation
2-1. Introduction
This section contains information and instructions
necessary for setting up the HP 16500A/16501A
Logic Analysis System. This includes inspection
procedures, power requirements, hardware
connections and configurations, and packaging
information.
2-2. Safety Considerations
The safety symbols used with Hewlett-Packard
instruments are illustrated in the front of this
manual. WARNING and CAUTION symbols and
instructions should be reviewed before operating
the instrument. These warnings and cautions
must be followed for your own protection and to
avoid damage to the instrument.
2-3. Initial Inspection
Inspect the shipping container for damage. If the
shipping container or cushioning material is
damaged, it should be kept until the contents of
the shipment have been checked for
completeness and the instrument has been
checked mechanically and electrically. The
contents of the shipment should be as listed in
"Accessories Supplied" in section 1. If the
contents are incomplete, if there is mechanical
damage or defect, or if the instrument does not
operate properly, notify the nearest
Hewlett-Packard Sales Office. If the shipping
container is damaged, or the cushioning material
shows signs of stress, notify the carrier as well as
the Hewlett-Packard Sales Office. Keep the
shipping material for carrier’s inspection. The
Hewlett-Packard Sales Office will arrange for
repair or replacement at Hewlett-Packard’s option
without waiting for a claim settlement.

the protective disks whenever the instrument is
transported.
2-5. Power Requirements
The HP 16500A and the HP 16501A each require
a power source of 115 Vac or 230 Vac, 48 to 66

2-8. User Interface
Four devices may be used to interface with the
HP 16500A and all installed modules, the
touchscreen, the front panel knob, the optional
keyboard, and the optional mouse. See figure 2-3.
For complete operating information refer to the
HP 16500A/16501A Logic Analysis System
Operation Reference Manual
and the Operating
Manual for each module installed.
The Touchscreen.
The touchscreen interface provides the main front
panel control or access to the menus. By touching
the appropriate field, you can access other menus,
configure the HP 16500A for making
measurements, and enter or change alphanumeric
data.
The Front Panel Knob
The front panel knob is used to increment or
decrement numeric fields and to roll the display.
Rolling the display means scrolling through
information on screen.
The Optional Mouse
The mouse is an optional user interface accessory
(HP 46060A). The mouse functions in the same
way as the touchscreen and the knob. Moving it
about on a hard, flat surface will move the cursor
over the entire screen. To select a field, connect
the mouse to the front panel HIL connector and
move the mouse until the cursor rests in the
desired field. Press the left button of the mouse to
complete the selection of the field. To duplicate
the knob function, press and hold the right button
of the mouse and move it over the desktop. When
the correct numerical value or the correct function
has been selected, stop moving the mouse and
release the right button.
The Optional Keyboard
The keyboard is an optional user interface
accessory (HP E2427A). The keyboard can be
used interchangeably with the knob, the
touchscreen, and the mouse for all menu
applications.
