At close-in distance, it is easier to determine the spectrum signature of EUT, and if applicable, the EUT configuration that emanate the maximum level of emissions. The data may not be precisely correlatable results. 5.3 Shielded enclosure To search the Radiated frequency outline of an EUT a shielded screen room may be used. If the shielded room is used for radiated data, the data page will state that the EUT was in a shielded enclosure. All data collected ina screen room for emission data, radiated emissions is for frequency outline only. If an EUT is placed in screen room for AC Powerline Conducted the data page will show that a screen room was used and data frequencies and levels will be correct and used for test data. 5.4 Data reporting format The measurement results expressed in accordance with C63.4 and specified limits where applicable arepresented in tabular or graphical form, or alternatively as recorder charts or photographs of a spectrum analyzer display, showing the level vs. frequency. 5.5 AC powerlineconductedemissiontest The EUT was connected to LISN. All supporting equipments were connected to another LISN. Preliminary Power line Conducted Emission test was performed by using the procedure in ANSI C63.4: to determine the worse operating conditions. 5.6 Radiated emission test Preliminary radiated emission test was conducted using the procedure in ANSI C63.4: to determine the worse operating conditions. Final radiated emission test was conducted at open area test site.

The EUT was connected to an artificial mains network (LISN) placed on the floor. The EUT was placed on non-metallic table 0.8 m above the metallic, grounded floor. Amplitude measurements were performed with a quasi-peak detector and an average detector Measurement uncertainty Conducted emission, quasi-peak detection: ± 1.79 db Conducted emission, average detection: ± 1.79 db The measurement uncertainty is given with a confidence of 95 % with the coverage factor, k = Test equipment used Equipment Model Serial No. Vendor Next Cal.

The final test was done at a 3 m open area test site with a quasi-peak detector. EUT was placed on a non-metallic table height of 0.8 m above the reference ground plane. Cables were folded back and forth forming a bundle 0.3 m to 0.4 m long and were hanged at a 0.4 m height to the ground plane. Cables connected to EUT were fixed to cause maximum emission. Test was made with the antenna positioned in both the horizontal and vertical planes of polarization. The measurement antenna was varied in height above the conducting ground plane to obtain the maximum signal strength Measurement uncertainty Radiated emission electric field intensity, 30 MHz ~ MHz: ± 4.00 db Radiated emission electric field intensity, above 1 GHz: ± 2.92 db The measurement uncertainty is given with a confidence of 95 % with the coverage factor, k = Test equipment used Equipment Model Serial No. Vendor Next Cal.
