Metering
the
power
level
When
you
are
measuring
a
device
that
is
very
sensitive
to absolute
power level,
it is
important
that
you
accurately
set
the
power
level
at
either the
device input
or output.
The analyzer
is
capable
of
using
an
external
HP-IB
power
meter and
controlling source
power directly
.
