.The
current
settings
of
the
Attenuator
can
be
read or
set.
The
attenuation
is a
number
from 0
to
23
where
the
number
specifies
the
multiple
of
6-dB
attenuation.
Zero
indicates
no
attenuation,
and
23 is
the
maximum
attenuation.
Only
the
attenuators
are
changed
with
the
"XB"
command.
The
value
of
the
attenuation
will
be
output
on
the "XA"
command as
an
unsigned
integer
followed
by
<E0R>.
