CALCULATIONS

EMISSIONS TESTING

Individual calibration data for the log periodic antenna is supplied at

appropriate distances (3, and 10 meter) 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V/meter.

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

IMMUNITY TESTING

For Immunity measurements, the generated electric field strength can be

calculated by:

REV B

SA = Spectrum Analyzer or Receiver voltage reading

AF = Antenna Correction Factor

CL = Cable Loss in dB

FS = Approximate Field Strength in (V/m)

P = Power in watts

g = Numeric Gain

d = Distance in meters
