INTRODUCTION
This section
of the
manual
describes the theory of operation for the Generator.
There
are
four
major
headings:
General Description
Functional Description
Software Operation
Detailed Circuit Descriptions
The General
Description briefly
explains the functions
and components
of the
three
major modules of the Generator.
The
Functional Description covers
the
main
output
parameters, amplitude, frequency,
and modulation.
The
Software Operation
section
describes the software
and
how
it
affects
the hardware.
The
Circuit
Description
is
a
comprehensive
explanation of the operation of
each
circuit
assembly.

GENERAL DESCRIPTION
The
Generator has
three
major sections.
The
front section includes the
keyboard and
display for local control.
The module
section includes the frequency,
level,
modulation,
and
control
circuits.
The
rear section includes the
power
supply, cooling
fan,
and
assorted
external connectors.
3-3.
Front Section
The
front section of the
Generator
provides the operator
interface.
It
includes the
primary
controls, connectors,
and
indicators
of the Generator, All front panel keys
and
displays
(except the
power
switch that controls the
power
supply
directly)
are
monitored and
handled by the Controller
in the
module
section.
3-4.
Module
Section
The module
section
is
a multi-compartmented,
shielded
enclosure that includes the
circuits
that generate the instrument stimulus functions:
frequency, modulation,
and
amplitude.
The
Controller
is
also located here.
The
Controller governs the
Generator
operation
and
at
power-on
determines
if
any
options
are installed
by checking the option
status
bits.
The
optional
Low-Rate
FM,
is
also located in this
section of the instrument.
3-5. Rear Section
The
rear section includes the
power
supply, the cooling fan,
various external connectors,
the
IEEE-488
Interface
and
the High-Stability Reference Options.
