Change and correction information in this supplement is itemized by page numbers corresponding to the
original manual pages. The pages in this supplement are organized in numerical order by manual page
number.
HOW TO USE THIS SUPPLEMENT
Insert this title page in front of the title page in your manual.
Perform all changes specified for “All Serials”, and all changes through the Series Prefix of your
instrument or board.
Insert any complete replacement pages provided into your manual in the proper location.
If your manual has been updated according to the last edition of this supplement, you need only per-

PLEASE NOTE
This instrument incorporates a new method for tracking changes to its circuit boards.
Starting July 1, 1988, all circuit boards will be labeled with a unique serial number. The
SERIAL number will replace the previously used SERIES number, even though there may
have been no change to the circuit board. Thus, if changes were made after July 1,
1988, they will be documented in this change sheet using the new circuit board SERIAL
number. Changes made before that time are documented with the SERIES number.
Therefore, Circuit changes described in this change sheet may reference either the older
SERIES number or the new SERIAL number. Using both numbers enables this change
sheet to support both older and newer products. To determine which changes apply to
your instrument, find the instrument’s serial number prefix located on the rear panel, and
make the manual changes indicated in this change sheet for that serial number prefix.
For example, if the serial number is 2804A12345, make changes to the manual indi-
cated for serial orefix 2804.

SAFETY CONSIDERATIONS
The 5087A Distribution Amplifier Safety Class I instrument (provided with a protective earth terminal),
designed and tested according to international safety standards. To ensure safe operation and to keep the
instrument in safe condition, the user must follow the information, cautions, and warnings provided below
in the Operating and Service Manual. WARNING
Before switching on this instrument, the protective earth terminal of the instrument must be co~eckd to
the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket
outlet provided with a protective earth contact. The protective action must not be negated by the use of an
extension cord (power cable) without a protective conductor (grounding).
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be
secured against any unintended operation.
All protective earth terminals, extension cords, autotransformers, and devices connected to this instrument
should be connected to a protective earth grounded socket outlet. Any interruption of the protective earth
grounding will cause a potential shock hazard that could result in personal injury.
For continued protection against fire hazard, replace the line fuse only with a 250V fuse of the same cur-
rent rating and type. Do not use repaired fuses or short circuited fuseholders.
Before switching on this instrument, make sure that it is adapted to the voltage of the ac power source.
Any maintenance or service requiring removal of protective covers should be performed by service-trained
personnel who are aware of the hazard involved (for example, fire and electrical shock).
Capacitors inside the instrument may still be charged even if the instrument has been disconnected from its
source of supply.

Model 5087A
General Information
SECTION I
GENERAL INFORMATION
1-I. INTRODUCTION
l-2. Description
l-3. The Hewlett-Packard Model 5087A is a narrow-band amplifier capable of receiving up to
four different input frequencies on three input channels. It amplifies these frequencies and
supplies outputs in any selected combination on a total of 12 output lines. Table l-4 lists the
assembly designation, description, function, where it is used, the corresponding HP part number
and its assigned option number.
l-4. The three input lines are labeled A, B, and C while the 12 outputs lines are labeled 1 through
12. Each input line, as well as the 12 output lines and the power supply voltage, may be moni-
tored by a front-panel meter through a 16-position front-panel switch.
1-5. All input and output connectors and fuses are mounted on the instrument rear panel. All con-
trols and indicators are mounted on the instrument front panel. Electrical and mechanical specifica-
tions are listed in Table l-l and equipment supplied is listed in Table l-3.
l-6. NORMAL CONFIGURATIONS AND OPTIONS
l-7. Normal Configurations
1-8. There are four Normal Configurations of input and output amplifiers, which consists of the
following:
a. Option 031: Three Input Preamplifiers and four each, 5 MHz, 1 MHz, and 100 kHz Out-
put Amplifiers.
b. Option 032: A single Input Preamplifier and 12, 5 MHz Output Amplifiers.
c. Option 033: A single Input Preamplifier and 12, 10 MHz Output Amplifiers.
d. Option 034: An Input Preamplifier, one 5 MHz to 1 MHz Divider, one 1 MHz to 100 kHz
Divider and four each 5 MHz, 1 MHz, and 100 kHz Output Amplifiers.
l-9. These configurations are shown by option number in Figure l-l, a, b, c, and d.
I-10. Options
1-11. In addition to the four available, normal configuration listed in Figure l-l, each input and
output printed circuit assembly is assigned an option number. For example:
Input positions (up to 3 total):
Option 004: Input Preamplifier (100 kHz to 10 MHz).
Option 005: 5 MHz to 1 MHz Input Divider.
Option 006: 1 MHz to 100 kHz Input Divider.
Option 011: 5 MHz to 10 MHz Input Doubler.
Option 013: 10 MHz to 5 MHz Input Divider.
Option 014: 10 MHz to 1 MHz Input Divider.
Output positions (up to 12 total):
Option 001: 5 MHz Output Amplifier.
Option 002: 1 MHz Output Amplifier.
Option 003: 100 kHz Output Amplifier.
Option 012: 10 MHz Output Amplifier.
