Mat:
The difficulty with this method is when you get an EUT emission that lands
right on an ambient emission. (Or close enough to include both signals in the
analyzer/receiver passband.) You may know that there's an EUT emission at that
frequency, but the ambient may exceed or even mask the EUT emission. And your
amplitude measurement is then corrupted.
