The
following
screenshot
shows
a
cursor
pair
placed
on
the
waveforms
display.
RearView
The
RearView
tool
allows
you
to
store
and
navigate
through
a
history
of
data
acquisitions
retrieved
from
the
device(s).
The
expanded
RearView
tool’s
detailed
control
looks
like
the
following:
RearView
keeps
a
history
of
the
last
N
acquisitions.
View
your
stored
acquisitions
by
setting
your
trigger
to
Stop
and
using
the
slider
on
the
detailed
control
to
flip
through
the
history.
The
currently
selected
acquisition
is
shown
in
the
waveform
display
area.
You
can
change
the
number
of
stored
acquisitions
by
providing
a
new
number
in
the
text
box
at
the
right
end
of
the
tool’s
detailed
control.
The
blue
bar
on
the
slider
control
displays
how
much
of
the
RearView
history
is
being
used
and
available
for
review.
This
bar
fills
up
as
you
make
new
acquisitions
until
reaching
your
specified
depth;
at
which
point
the
oldest
acquisition
is
discarded
when
a
new
one
is
received.
Note
:
The
RearView
tool
is
always
enabled.
The
default
acquisition
depth
is
set
to
20
records.
The
specific
acquisition
being
viewed
is
always
shown
above
the
slider
control
–
for
example
in
the
previous
screenshot
the
tool
is
showing
acquisition
11
of
20
possible
acquisitions.
When
you
acquire
a
new
acquisition
the
RearView
tool
automatically
adjusts
to
show
the
most
recent
acquisition.
TIPS
:
•
While
using
the
RearView
tool,
you
can
modify
your
signal
setup
at
any
time
and
display
additional
signals/data
in
different
ways
than
how
it
may
have
been
set
at
the
time
of
the
actual
signal
acquisition.
•
You
can
create
a
persistence
display
to
compare
acquisitions
AFTER
all
the
necessary
acquisitions
have
been
obtained.
Do
this
by
enabling
persistence
mode,
and
then
navigating
through
various
acquisitions
available
in
the
RearView
tool.
You
can
even
generate
a
persistence
display
for
a
timeframe
or
zoom
level
–
even
if
the
signal
data
was
not
yet
visible
at
the
time
of
acquisition.
