The
U11
command
indicates
the
present
number
of
measure values
in
the
sweep
buffer
and
is
formatted as
shown
in
Figure 3-25.
This
information
is useful
when
a
sweep
has
aborted
and
further measurements are unavailable. The value returned
by
U10 can
be
used
as
the
count
in
a FOR/NEXT loop to obtain single lines of sweep
data.
