Emission test site validation (draft ANSI C63.4a) and antenna calibration (ANSI C63.5) workshops

These two workshops are combined into one day covering these topics: (1) review of the updated emission test site validation procedure between 30 MHz and 1 GHz using the so-called normalized site attenuation (NSA) approach. This is intended to replace what is in Annex D in C63.4-2014 and (2) description of the recently published ANSI C63.5 covering antenna calibration and replacing the 10-year-old version of that standard. These workshops are designed to increase your understanding of the updated Annex D in C63.4 and the modifications in the 2006 edition of C63.5 covering antenna calibrations for making emission measurements. For the C63.4a workshop, key changes include performing NSA measurements at 5 meters, highlighting the requirement to have NSA performed with NSA transmit antennas at the height of the equipment being tested, and better defining the maximum frequency intervals in the measurement process. For the C63.5 workshop, the major changes made to the 2006 edition will be presented. These include a new section covering free space correction terms for tuned dipole antennas and biconicals, and one covering calibration frequency spacing. Completely new to C63.5 is a section on the use of time-gating to determine free-space antenna factors above 1 GHz. Several annexes have been added on the site comparison approach. Calibration site requirements and qualifications for hybrid antennas will be explained.
