Introduction
The
controller
assemblies perform
all
digital
data
transfer
and
control functions
for
instrument
opera¬
tion.
Interface
circuitry
provides communication
with the
rest
of
the
instrument.
Digital
Information
is
exchanged
between
the
instrument
processor
and
other
sections
of
the
instrument
on
a
bidirectional
data
bus.
Rear
panel
interface signals
(e.g.
HP-IB,
sweep
output)
are
routed through
or
generated
in
the
con¬
troller functional
group.
Sweep
control
signals
initiated
by
the
controller
section
start
and
stop
the
sweep
generator.
Sweep
events
(e.g.
bandcrossings,
end of
sweep,
markers)
are
monitored
by
the
controller section and
specific instructions
are executed
according to
the
type
of
sweep
event.
ASSEMBLIES

controller
functional
group
consists
of
three
assemblies:
•
A57

assembly
•
A59

interface assembly
•
A60
instrument
processor
assembly
The
A60
