APPENDIX A. 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).
