Field Strength Calculation (cont’d)
Example
Assume a receiver reading of 62.0dB
µ
V is obtained. The antenna factor of
7.4dB and cable factor of 1.6dB is added. The amplifier gain of 29dB is
subtracted. The pulse desensitization factor of the spectrum analyzer was
0dB, and the resultant average factor was
−
10dB. The net field strength for
comparison to the appropriate emission limit is 32dB
µ
V/m. This value in
dB
µ
V/m was converted to its corresponding level in
µ
