Choosing

and

Time
Depolarization
application
When
using
scan
rate
8,
the
polarization
state
at
the
output
of
the
Agilent
11896A
is
changing
fast
enough
to
act
as
a
depolarizer
for
detectors
with
a
long
averaging
time
.
A
detector
averages
over
many
polarization
states
during
its
averaging
time
and
the
polarization-dependent
responsivity
(PDR)
of
the
detector
is
reduced
or
eliminated.
A
detector
averaging
time
of
two
seconds
is
sucient
to
reduce
the
detector
PDR
by
a
factor
of
ten.
F
or
example
,
a
detector
with
an
averaging
time
of
two
seconds
and
a
0.020
dB
PDR
with
no
depolarizer
has
a
0.002
dB
PDR
when
preceeded
with
the
Agilent
11896A
using
scan
rate
8.
A
veraging
times
of
less
than
one
second
are
insucient
to
substantially
reduce
the
detector
PDR.
