LEARN
STRING
COMMANDS
The
following
learn
string
commands
instruct
the
analyzer
to
transmit
its
internal
configuration,
state
acquisition
data,
and/or
timing
acquisition
data
to
the
controller
.
Learn
string
commands
provide
a
means
of
saving
configurations
and
acquisition
data
for
later
use
and
analysis
.
Measurement
configurations
can
be
stored
and
reloaded
to
repeat
complexmeasurements
.
Likewise,
acquisition
data
can
be
returned
to
the
analyzer
for
analysis
at
a
more
convenient
time
.
You
need
only
transmit
the
learn
string
back
to
the
analyzer
to
restore
configuration
or
an
acquisition
.
The
learn
string
is
transmitted
asa
receive
learn
string,
that
is,
nothing
needbe
added
or
changed
in
the
learn
string
in
order
to
return
it
to
the
logic
analyzer
.
Each
learn
string
contains
the
proper
mnemonic
header
(RS,
RT,
RA)
to
receive
state
or
timing
data,
a
binary
byte-count
word,
the
binary
data,
and
two
Cyclic
RedundancyCheck(CRC)
bytes
.
The
binary
byte-count
word,
returned
most
significant
byte
(MSB)
first
and
least
significant
byte
(LSB)
last,
gives
the
numberof
bytes
contained
in
the
binary
data
file,
including
the
two
CRC
bytes
but
notthe
byte
count
word
or
the
mnemonic
.
