GLOSSARY
SIGNATUR
:
A number which is
a
function
of
the data
nd
the sequence of data
in
memory.l lt
is
derived using an algorithm
which
a*ures
a 99.998% probability
that
if
either
th*
data
or its sequence changes, the
signaturO
changes.
THROUGHFUT:
The
throughput rate
is
the
rate at which
a measurement can be made,
scaled tq
engineering units, and the reading
stored
inl
Final
Storage.
The
21X has the
ability
to]scan sensors at a rate exceeding
the
thro{ghput
rate (see
SAMPLE RATE).
The
priftary factor
affecting
throughput
rate
is
tfie amount of processing specified
by
the
u$er.
In
normal operation, all
processipg called
for by an instruction must
be
comfleted before
moving on
the next
instructiqn. The maximum throughput rate
for
a
fasl single-ended measurement
is
256
measurqments per
second (16
measurqments,
16
times per second).
