CERPASS TECHNOLOGY CORP. Report No.: TEFO1806258 6.2. Test Procedures a. The EUT was placed on a rotatable table top 0.8 meter above ground. b. The EUT was set 3 meters from the interference receiving antenna which was mounted on the top of a variable height antenna tower. c. The table was rotated 360 degrees to determine the position of the highest radiation. d. The antenna is a broadband antenna and its height is varied between one meter and four meters above ground to find the maximum value of the field strength both horizontal polarization and vertical polarization of the antenna are set to make the measurement. e. For each suspected emission the EUT was arranged to its worst case and then tune the antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the maximum reading. f. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function and specified bandwidth with Maximum Hold Mode. g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions which do not have 3 dB margin will be repeated one by one using the quasi-peak method and reported. h. “Cone of radiation” has been considered to be 3dB beamwidth of the measurement antenna.
