The office of Engineering and Technology, Laboratory Division, released a public draft review regarding proper antenna calibration procedure.
The document answers the question;
“What procedure should be used to calibrate antennas used to make radiated emission measurements and normalized site attenuation (NSA) measurements”?
According to the public draft review, the revised ANSI standard, ANSI C63.5-2006 provides the proper procedure and is based on a horizontally polarized measurement performed on a standard antenna calibration site at a 10 meter distance.
Antenna factors collected in this manner can then be used for vertical or horizontal measurements at distances of 3 meters or more.
