7 For an over the air measurement,
connect an antenna and an external
filter to the RF input.
The external filter is necessary to
eliminate out-of-band signals that
would otherwise reduce the dynamic
range of measurements in the band
of interest. The effect of the
out-of-band signals is to raise the
noise floor, possibly hiding some or
all of the signal of interest.
