INTRODUCTION
CAPTURING
A
STATE
TRACE
Chapter
4
State
Measurements
The
1630A/D/G
Logic
Analyzers
are
capable
of
capturing
large
quantities
of
data
.
To
make
this
data
useful,
the
incoming
data
needs
to
be
formatted
in
an
arrangement
that
is
easily
comprehensible
.
This
is
accomplished
with
the
1630A/D/G
analyzers
by
grouping
the
incoming
lines
and
labeling
the
groups
for
the
typical
connections
for
the
address,
data,
status,
and
other
lines
of
interest
.
Incoming
data
may
be
further
identified
by
assigning
user
defined
labels
for
conditions
rather
than
the
provided
bases
of
hexidecimal,
binary,
or
ASCII
.
Another
type
of
user
base
may
be
assigned
in
which
relocatable
code
is
labeled
by
the
user
.
The
next step
in
making
the
captured
data
useful
is
to
edit
the
data
before
it
is
stored
by
the
analyzer
.
Selective
tracing
techniques
are
used
for
recognizing
and
storing
only
qualified
data
.
The
1630A/D/G
Logic
Analyzers
provide
a
trace
specification
menu
in
which
resource
terms
may
be
identified
for
selective
tracing
.
Resource
terms
may
be
specified
for
simple
triggering,
sequence
triggering,
sequence
restart,
and
store
qualifying
.
The
target
system
used
throughout
this
manual
for
examples
is
the
HP
Model
5036A
Microprocessor
Lab
which
contains
an
8085
microprocessor
.
All
traces
shown
in
the
figures
are
from
the
5036A
.

.
Make
all
the
required
connections
to
the
target
system
.
Information
for
connecting
the
probes,
directly
or
through
an
interface,
is
in
chapter
2
of
this
manual
.

Apply
operating
power
to
the
logic
analyzer
and
to
the
target
system
.
NOTE
When
using
a
preprocessor,
be
sure
to
apply
power
to
the
analyzer
first
or
the
target
system
may
not run
.
The
logic
analyzer
will
execute
power-up
sequences
and
display
the
system
menu
in
the
default
configuration
.
The
1630G
will
also
display
messages
indicating
what
is
being
loaded
from
internal
storage
when
it
has
been
instructed
to load
internal
configurations
or
an
inverse
assembler
.
See
Power-
up
Display
Messages
in
chapter
2
for
more
information
on
the
power-upsequence
and
messages
.
The
default
system
configuration
assigns
all
channels
to state
measurement
and
none
to
timing
measurements
.
Figures
4-1a
and
4-1b
are
the
default
System
Specification
menus
for
the
1630D
and
1630G
.
The
1630A
default
System
Specification
menu
has
eight
less
channels
than
the
1630D
.
Power-
up
display
messages
will
appear
on
the
display
only
when
the
analyzer
is
powered
up
.

.
Press
RUN
.
The
logic
analyzer
will
execute
a
single
trace
and
display
a
State
Listing
in
hexadecimal
.
The
measurement
ensures
the
logic
analyzer
is
connected
to
the
target
system
and
the
target
system
is
running
.
Figures
4-2a
and
4-2b
are
examples
of
the
state
traces
that
will
be
displayed
when
collecting
a
free-run
trace
with
the
logic
analyzer
.
The
State
Listing for
the
1630G
has
more
columns
than
the
1630A/D
because
it
has
more
state
channels
and
a
counting
function
.
