Glossary
acquisition Denotes one
complete
cycle of data
gathering by a
module. For
example, in
the HP 16532
oscilloscope,
one complete
cycle gathers
8000 samples
of information
and stores
them in
acquisition
memory.
arm The arm
output from a
module is set
false when the
module begins
running and is
set true when
the module
finds its
trigger
condition.
Other
measurement
modules that
take the arm
signal as an
input are
unable to
capture data
or search for
their triggers
until they
receive their
arm signal.
The arm
signal is
usually used
to coordinate
measurement
start between
two or more
measurement
modules.

field.
autoscale algorithmAn algorithm
for
oscilloscope
modules that,
based on the
amplitude and
period of the
signals found,
sets the
vertical
sensitivity in
volts per
division,
offset,
horizontal
sweep speed
in seconds per
division,
trigger level,
and trigger
slope for the
trigger input.
