Operation Model 8901B
Detailed Operating Instructions Section
The
Detailed Operating Instructions
provide a complete operating reference for the Modulation Ana-
lyzer user. The instructions are organized into tabbed sections oriented
toward
specific measurement
types. Besides information on the various measurements, the instructions contain individual discus-
sions of nearly all controls, inputs, and outputs. Also included are instructions for using the many
user special functions.
A
guide
to
using the
Detailed Operating Instructions
is
provided ahead of the
instructions themselves.
Other Sources of Operating Information
Pull-Out
Cards.
The
Operating Information
and
Special finction Information Pull-Out Cards
are
flexible plastic reference sheets attached
to
the Modulation Analyzer by
a
tray located beneath the
front panel. They contain a brief summary of front-panel operation and displays.
Also
included on the
cards
is
a
complete listing
of
HP-IB codes,
data,
and error output formats, error codes, and user special
functions. The cards show a simplified block diagram for the Modulation Analyzer and provide basic
instructions for RF Power and AM and FM Measurements. The pull-out cards are intended
to
be
a
reference for the user who already has a basic understanding of front-panel operation.
Supplemental Information.
Other information, pertinent
to
operating the Modulation Analyzer
to
its fullest capabilities, are contained
in
Section
1.
“Principles of Operation for
a
Simplified Block
Diagram” (in paragraph 1-10) is a fundamental description of what the Modulation Analyzer
is
and
how
it
works. This information supplements the block diagrams provided
on
the pull-out card and
in
the
Detailed Operating Instructions.
“Modulation Basics”
(in
paragraph
1-11)
is
a discussion about
the way the Modulation Analyzer makes modulation measurements.
All
of this information helps
to
provide a basis for applying the Modulation Analyzer
to
various measurement situations.

OPERATOR’S INFORMATION
Fuses
For
continued protection against fire hazard, replace the line fuse only with
a
250V
normal blow fuse of the same rating. Do not use repaired fuses
or
short-circuited fuseholders.
The only maintenance the operator should normally perform
is
the replacement of the primary power
fuse located within the Line Power Assembly (A30). For instructions on how
to
change the fuse, refer
to Figure 2-1, steps
1
and
3.
Fuses can be ordered using HP part number 2110-0083, 2.5A (250V, normal blow) for 100/120 Vac
operation
or
2110-0043, 1.5A (250V, normal blow)
for
220/240 Vac operation.
