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
