3.1 Field Strength Calculation
The field strength is calculated by adding the reading on the Spectrum Analyzer
to the factors associated with preamplifiers (if any), antennas, cables, pulse
desensitization and average factors (when specified limit is in average and
measurements are made with peak detectors). A sample calculation is
included below.
FS = RA + AF + CF - AG + PD + AV
where FS = Field Strength in dBµV/m
RA = Receiver Amplitude (including preamplifier) in dBµV
CF = Cable Attenuation Factor in dB
AF = Antenna Factor in dB
AG = Amplifier Gain in dB
PD = Pulse Desensitization in dB
AV = Average Factor in -dB
In the radiated emission table which follows, the reading shown on the data
table may reflect the preamplifier gain. An example of the calculations, where
the reading does not reflect the preamplifier gain, follows:
FS = RA + AF + CF - AG + PD + AV
