6. Test of Radiated Emission Radiated emissions from 30 MHz to 25000 MHz were measured with a bandwidth of 120 khz for 30MHz to 1GHz, 1MHz for above 1GHz according to the methods defines in ANSI C63.4-2001. The EUT was placed on a nonmetallic stand, 0.8 meter above the ground plane, as shown in section 6.3. The interface cables and equipment positions were varied within limits of reasonable applications to determine the positions producing maximum radiated emissions. 6.1 Major Measuring Instruments Amplifier (HP 8447D) RF Gain 30 db Signal Input 100 KHz to 1.3 GHz Amplifier RF Gain Signal Input (MITEQ AFS44) 40 db 100 MHz to 26.5 GHz Spectrum analyzer Attenuation Start Frequency Stop Frequency Resolution Bandwidth Video Bandwidth Signal Input (R&S FSEK30) 10 db 1 GHz 25 GHz 1 MHz 1 MHz 20 Hz to 40 GHz Test Receiver Resolution Bandwidth Frequency Band Quasi-Peak Detector (SCHAFFNER SCR3501) 120 KHz 9 K 1 GHz ON for Quasi-Peak Mode OFF for Peak Mode SPORTON International Inc. Page No. : 20 of 20
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 half wave dipole 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 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. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than average limit (that means the emission level in peak mode also complies with the limit in average mode), then testing will be stopped and peak values of EUT will be reported, otherwise, the emissions will be measured in average mode again and reported.
