11 2.5 EUT Operation Test Setup For WLN RF test items, an engineering test program was provided and enabled to make EUT continuous transmit/receive. For C power line conducted emissions, the EUT was set to connect with the Notebook under large package sizes transmission. 2.6 Measurement Results Explanation Example For all conducted test items: The offset level is set in the spectrum analyzer to compensate the RF cable loss and attenuator factor between EUT conducted output port and spectrum analyzer. With the offset compensation, the spectrum analyzer reading level is exactly the EUT RF output level. Example: The spectrum analyzer offset is derived from RF cable loss and attenuator factor. Offset = RF cable loss + attenuator factor. Following shows an offset computation example with cable loss 5.3 db and db attenuator. Offset(dB) = RF cable loss(db) + attenuator factor(db). = = 25.3 (db) SPORTON INTERNTIONL INC. Page Number : of 36

The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 5. Corrected Reading: ntenna Factor + Cable Loss + Read Level - Preamp Factor = Level 6. For testing below GHz, if the emission level of the EUT in peak mode was 3 db lower than the limit specified, then peak values of EUT will be reported, otherwise, the emissions will be repeated one by one using the CISPR quasi-peak method and reported. 7. For testing above GHz, the emission level of the EUT in peak mode was db lower than average limit (that means the emission level in average mode also complies with the limit in average mode), then peak values of EUT will be reported, otherwise, the emissions will be measured in average mode again and reported. 8. Use the following spectrum analyzer settings: () Span shall wide enough to fully capture the emission being measured; (2) Set RBW= khz for f < GHz; VBW RBW; Sweep = auto; Detector function = peak; Trace = max hold; (3) Set RBW = MHz, VBW= 3MHz for f GHz for peak measurement.
