A.H. Systems Model SAS-562B Active Loop Antenna

CALCULATIONS

EMISSIONS TESTING

Individual calibration data for the active loop antenna is supplied to comply

with various emissions test requirements. For emissions measurements, add

antenna factor plus cable loss to receiver reading in dBV to convert to field

strength in dBA/meter.

Field Strength(dBuA/m) = SA(dBuV) + MAF(dB/m) + cable loss (dB)

Fictitious electric field strength can be calculated by the following:

SA = Spectrum Analyzer or Receiver voltage reading

MAF = Magnetic Antenna Correction Factor

CL = Cable Loss in dB

dBV/m = dBA/m + 51.5
