The measuring distance of 3 m shall be used for measurements. The EUT was placed on the top of a rotating table 0.8 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation.(below 1GHz) b. The measuring distance of 3 m shall be used for measurements. The EUT was placed on the top of a rotating table 1.5 meter above the ground at a 3 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation.(above 1GHz) c. The height of the equipment or of the substitution antenna shall be 0.8m or 1.5m; the height of the test antenna shall vary between 1 m to 4 m. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights find the maximum reading (used Bore sight function). e. The receiver system was set to peak and average detect function and specified bandwidth with maximum hold mode when the test frequency is above 1GHz. f. The initial step in collecting radiated emission data is a receiver peak detector mode pre-scanning the measurement frequency range. Significant peaks are then marked and then Quasi Peak detector mode re-measured. g. All readings are Peak unless otherwise stated QP in column of Note. Peak denotes that the Peak reading compliance with the QP Limits and then QP Mode measurement didn`t perform. (below 1GHz) h. All readings are Peak Mode value unless otherwise stated AVG in column of Note. If the Peak Mode Measured value compliance with the Peak Limits and lower than AVG Limits, the EUT shall be deemed to meet both Peak & AVG Limits and then only Peak Mode was measured, but AVG Mode didn`t perform. (above 1GHz) i. The test result is calculated as the following: (1) Result = Reading + Correct Factor (2) Correct Factor = Antenna Factor + Cable Loss Amplifier Gain + Attenuator (3) Margin = Result - Limit Spectrum Parameter Attenuation Start Frequency Stop Frequency RBW / VBW (Emission in restricted band) Setting Auto 1000 MHz 10th carrier harmonic RBW 1MHz VBW 3MHz peak detector for Pk value RMS detector for AV value Receiver Parameter Attenuation Start ~ Stop Frequency Start ~ Stop Frequency Start ~ Stop Frequency Start ~ Stop Frequency Start ~ Stop Frequency Setting Auto 9 kHz~90 kHz for PK/AVG detector 90 kHz~110 kHz for QP detector 110 kHz~490 kHz for PK/AVG detector 490 kHz~30 MHz for QP detector 30MHz~1000MHz for QP detector Page 18 of 61 Report No.: 24EFSS11090 04401 5.3 MEASUREMENT INSTRUMENTS LIST Item Equipment 1 EMI Test Receiver 2 Spectrum Analyzer 3 Loop antenna 4 Broadband antenna 5 HORN ANTENNA 6 Preamplifier Amplifier 7 PRE-AMPLIFIER 8 RF Cable 9 RF Cable 10 RF Cable 11 RF Cable 12 Measurement Software 5.4 TESTSETUP Manufacturer R&S Agilent SCHWARZBECK K SCHWARZBECK SCHWARZBECK HP EMEC R&S R&S R&S R&S Farad Model No. ESCI E4407B FMZB1519 VULB9168 BBHA9120D 8447F EM01G26G Test Cable 4 Test Cable 5 Test Cable 9 Test Cable 10 EZ-EMC (Ver.ATT-03A) Serial No. 101307 US40240708 1519-062 VULB9168-192 9120D 1065 3113A05680 980136 4 5 9 10 N/A Calibrated until 06/05/2025 11/17/2025 03/30/2025 03/29/2025 03/29/2025 11/17/2025 03/29/2025 11/17/2025 11/17/2025 04/17/2025 04/17/2025 N/A 9 kHz-30 MHz 30 MHz to 1 GHz 0.8 m EUT Absorbers 3 m Ground Plane 1-4 m 1 m Receiver Amp.
