b) Emission frequencies above 1 GHz
Radiated emission frequencies above 1 GHz to 5 GHz were too low to be measured
with a pre-amplifier of 35 dB.
4.5 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor, High Pass Filter Loss(if
used) and Cable Loss, and subtracting the Amplifier Gain (if any) from the measured
reading. The basic equation calculation is as follows:
Result = R Corrected Factor
where
Corrected Factor = Antenna Cable Loss + High Pass Filter Loss - Amplifier
Gain
