Example:
The
:WAVEFORM:POINTS
query
returns
the
points
value
in the
currently
selected
waveform
preamble.
The
points
value
is
the
number
of
time buckets contained
in
the
waveform
selected
with the
WAVEFORM:SOURCE
command.
In
most cases
the
number
of
time buckets
actually acquired
will
be
the
number
of
points
set in the
ACQUIRE
subsystem.
There
are
some
sweep
speeds
where
the
actual
number
of
points
will
be
less
than
requested.
These
are
shown
below.
With
the
sweep
speed
set to
2
ns
per
division
the
number
of
points
actually
acquired
will
be
32,64,128,
or
200.
With
the
sweep
speed
set to
5
ns
per
division
the
number
of
points
actually
acquired
will
be
32,64,128,256,
or
500.
With
the
sweep
speed
set
to
10
ns
per
division the
number
of
points
actually
acquired will
be
32,64,128,256,500,512,
or
1000.
