ORGANIZATION
This
section ot the manual contains
a functional
description of the circuitry
used in the 465B Oscilloscope.
It begins with
a general summary of the instrument, using
the basic block
diagram shown in Figure
3-1
As an
additional reference,
a comprehensive overall block
diagram is provided
in
the
tabbed Diagrams section at the
back of this manual.
interrelationships
with front panel controls. Schematic
diagrams also are provided in the Diagrams section
of the
manual and are keyed to their
respective circuit descrip-
tions by numbered diamond symbols. For
optimum un-
derstanding of the
circuit
being
described, you should
refer to both the appropriate schematic diagram
and
functional block diagram
INTEGRATED CIRCUIT
DESCRIPTIONS
Each major

connections
between parts comprising the
circuit, to
