Diode
Detector
Leveling
Setup
When
external
diode
detector
leveling
is
chosen,
power
is
sampled
at
the
external
sampling
device
(either
a
directional
coupler
or
power
splitter)
by
an
external
diode
detector
that
is
typically
operating
in
the
square
law
region.
When
the
diode
detector
is
operating
in
the
square
law
region,
it
will
provide
a
DC
voltage
that
is
proportional
to
the
power
sampled
at
the
input
to
the
detector
.
This
DC
voltage
is
fed
back
to
the
synthesizer
via
the
ALC
IN
connector
.
The
synthesizer
then
adjusts
its
output
power
level
to
maintain
a
constant
power
level
at
the
input
to
the
external
diode
detector
.
Applications
External
leveling
can
be
used
when
your
application
requires
long
cables
that
will
cause
frequency-dependent
losses
.
It
also
enables
devices
,
such
as
ampliers
,
mixers
,
etc.
to
be
inserted
into
the
RF
signal
path
so
that
the
output
of
the
inserted
device
is
controlled
by
the
synthesizer
.
