OPERATION
3-1.
INTRODUCTION TO THIS SECTION
This section provides advanced operating information for the Modulation Analyzer. Included in this
section are descriptions of all front
and
rear-panel controls, connectors, and indicators, remote and
local operator’s checks, operating instructions, and operator’s maintenance.
Local Operation Section
Information regarding front-panel operation of the Modulation Analyzer is provided in the sections
described in the following paragraphs.
To
most rapidly learn the basic operation of the instrument,
refer
to
the separate
Basic Operation and Application Guide
and/or perform the
Operator’s Checks.
Once familiar with the general operation of the instrument, use the
Detailed Operating Instructions
for
the most in-depth and complete information on operating the Modulation Analyzer.
Remote Operation Section
The Modulation Analyzer is capable
of
remote operation via the Hewlett-Packard Interface Bus
(HP-IB). Provided in this section are instructions pertinent
to
HP-IB operation including
all
specific
considerations and instructions (including capabilities, address formats, input and output formats, the
status byte, and service requests).
At
the end
of
the discussion
is
a complete summary of all codes
and formats.
HP-IB information concerning remote information
also
appears in several other locations. Address
setting
is
discussed in Section
2,
a summary
of
HP-IB codes and output formats appears on the
Operating Information
pull-out card, and a list
of
relevant program codes for each function appears
in the
Detailed Operating Instructions.
(Detailed Operating Instructions are described above in the
paragraph,
Local Operation Section.)
Basic Functional Checks Section.
Basic finctional Checks
are simple procedures designed
to
be performed by the operator. These checks
verify the proper operation of the Modulation Analyzer’s main functions and HP-IB capabilities.
These checks can also be used
to
familiarize the first-time operator with basic Modulation Analyzer
measurements and HP-IB capabilities.
Two
procedures are provided
Basic Functional Checks
of
the Modulation Analyzer.
This procedure assures that most front-panel
controlled functions are being properly executed by the Modulation Analyzer. The checks require the
use of a sensor module, a signal generator, an oscilloscope, and interconnecting cables and adapters.
Basic Functional Checks
of
the Hewlett-Packard Interface Bus (HP-IB)
This series of procedures requires only an HP-IB compatible computing controller and an HP-IB
interface and connecting cable. The
HP-IB finctional Checks
assume that front-panel operation has
been
verified (for example, by performing the
Basic finctional Checks).
