detectors:
While
the
detector
is
specied
down
to
10
MHz,
the
power
sensor
used
in
this
procedure
is
only
calibrated
down
to
50
MHz.
If
data
is
required
below
50
MHz,
characterize
the
power
sensor
to
1
0
MHz,
or
use
an
additional
power
sensor
which
covers
this
frequency
range
,
and
correlate
the
results
with
the
data
above
50
MHz.
