If
you
use
a
directional
coupler to
sample power
in your
measurement
conguration,
you
should
enter
the
coupled
arm
power loss
value into
the power
loss table
,
using
the
following
procedure
.
Y
ou
can
enter the
loss information
in a
single segment,
and
the
analyzer
will
assume
that
the
value
applies
to
the
entire
frequency range
of the
instrument.
Or
,
you
can
input
actual

power
loss
values
at
several
frequencies
using up
to 55
segments
,
enhancing

Remember
to
subtract

from
the

entering
it

to
ensure
the

4. Repeat the previous two steps to enter up to 55 frequency segments
, depending on the
required accuracy
.
You may enter multiple segments in any order because
the analyzer automatically sorts them
and lists them on the display in increasing order of frequency
.
If you only enter one frequency segment, the analyzer assumes that the
single value is valid
over the entire frequency range of the correction.
