3.1 Field Strength Calculation (cont’d)
Example
Assume a receiver reading of 62.0 dBµV is obtained. The antenna factor of 7.4
dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is
subtracted. The pulse desensitization factor of the spectrum analyzer was 0
dB, and the resultant average factor was -10 dB. The net field strength for
comparison to the appropriate emission limit is 32 dBµV/m. This value in dBµV/m
was converted to its corresponding level in µV/m.
RA = 62.0 dBµV
AF = 7.4 dB
CF = 1.6 dB
AG = 29.0 dB
PD = 0 dB
AV = -10 dB
FS = 62 + 7.4 + 1.6 - 29 + 0 + (-10) = 32 dBµV/m
Level in µV/m = Common Antilogarithm [(32 dBµV/m)/20] = 39.8 µV/m
