is
a

approximation
made
up
of
10
linear

width
is
one
decade
of
frequency.
NOTE
The
actual
Stop
Frequency
at
the
end
of
a
Single
Log
Sweep,
will
be
higher
than
the
programmed
value
because
of
computation
time
required
by
the
control
circuits.
The
actual
value
will
always
be
within
0.25%
of
the
programmed
value
and
the
error
will
decrease
as
the
sweep
time
increases.
