VNA type analyzers *still have broadband detectors* and are not
immune from broadcast interference if the broadcast signal is
sufficiently stronger than the source (sweep) signal.  Performance
of the VNA type analyzers depends on the resolution of the ADC,
the ratio of the desired to undesired (interfering) signal and the
ability of the software to distinguish between the two.
