8 3 OPERTIONL STTES ND PHYSICL BOUNDRIES The EUT is a WLN module, which is intended to be used in several applications. ll radiated tests were carried out with samples with integral antenna (cb No. 6 and cb No. 5) and samples with external antenna (cb No. 4 and cb No.). The conductive tests were carried out at the U.FL connector of the samples with external antenna port. During all tests the EUT was powered with 5. V DC via the carrier board. The operation mode was adjusted with the help of a configuration-software on a laptop computer. For setting the equipment into the necessary operation mode, the computer was connected temporary to the SPI / SDIO interface of the WLN module via RS 232 to the adapter board. fter adjusting the required operation mode, the adaptor board could be removed. The EUT contains also a 5 a- and n-mode WLN. Object of this test report is the 2.4 b-, g- and n-mode WLN only. The results of the measurements of the 5 WLN will be documented in a separate test report. For adjusting the output power with the test software, a power setting of 58 was used during all tests. During the tests, the EUTs were not labelled with an FCC/IC-label. The following operation modes were used during the tests: Operation mode Description of the operation mode 1 Continuous transmitting on 2412 MHz, g, b or n-mode, with all applicable data rates 2 Continuous transmitting on 2437 MHz, g, b or n-mode, with all applicable data rates 3 Continuous transmitting on 2462 MHz, g, b or n-mode, with all applicable data rates 4 Continuous receiving on 2412 MHz 5 Continuous receiving on 2437 MHz 6 Continuous receiving on 2462 MHz Physical boundary of the EUT Wireless LN module cb /3 Carrier board cb-93-3 SPI / SDIO dapter board cb RS 232 Laptop computer with configurationsoftware 5.

Therefore all radiated tests were carried out in three orthogonal directions to cover hand held applications. The results in this test report are showing the maximum of these three measurements. For the orientation during the test, please refer also the photographs in annex of this test report. The EUT is available with two different power supply circuits. The conducted emission measurement on the power supply line as well the radiated emission measurements were showing no noticeable difference between the variants. There for they were not documented separately. lso the use of the SPI interface (cb-926-2) shows no measurable difference to the use of the SDIO interface (cb-926-3).

26 6.4 BND-EDGE COMPLINCE METHOD OF MESUREMENT (BND-EDGE COMPLINCE) The calibration of the spectrum analyser has to be checked with the help of a known signal from a signal generator. The EUT has to be connected to the antenna, which causes the highest field strength on the wanted frequency. The following spectrum analyser settings shall be used: - Span: Wide enough to capture the peak level of the emission on the channel closest to the band-edge, as well as any modulation products, which fall outside the assigned frequency band. - Resolution bandwidth: khz. - Video bandwidth: the resolution bandwidth. - Sweep: uto. - Detector function: Peak. - Trace mode: Max hold. The same test set-up as used for the final radiated emission measurement shall be used (refer also subclause of this test report). The measurements shall be carried out with using a resolution bandwidth of khz. fter trace stabilisation the marker shall be set on the signal peak. The first display line has to be set on this. The second display line has to be set below the first line (or the peak marker). The frequency line shall be set on the edge of the assigned frequency band. Set the second marker on the emission at the band-edge, or on the highest modulation product outside of the band, if this level is higher than that at the band-edge. This frequency shall be measured with the EMI receiver as described in subclause of this test report, but khz resolution bandwidth shall be used. The measurement will be performed at the upper end of the assigned frequency band. The plots at the next pages are showing radiated band-edge compliance with the worst case operation mode. The display line 1 (D1) in these plots represents the highest level within the assigned frequency band. The display line 2 (D2) represents the offset to this highest level and shows the compliance with FCC 47 CFR Part (d). The frequency line 1 (F1) shows the edge of the assigned frequency. The following tables are showing the results for the radiated band edge compliance for all applicable operation modes with the worst case data rate, causing the highest emissions at the band edges.

39 6.5 RDITED EMISSIONS METHOD OF MESUREMENT (RDITED EMISSIONS) The radiated emission measurement is subdivided into five stages. - preliminary measurement carried out in a fully anechoic chamber with a fixed antenna height in the frequency range 9 khz to 1. - final measurement carried out on an outdoor test side without reflecting ground plane and a fixed antenna height in the frequency range 9 khz to 3 MHz. - final measurement carried out on an open area test side with reflecting ground plane and various antenna height in the frequency range 3 MHz to 1. - preliminary measurement carried out in a fully anechoic chamber with a variable antenna distance and height in the frequency range 1 to final measurement carried out in a fully anechoic chamber with a fixed antenna height in the frequency range 1 to 25. ll measurements will be carried out with the EUT working on the middle and upper and lower edge of the assigned frequency band. For this reason the hopping function of the EUT has to be disenabled. Preliminary measurement (9 khz to 3 MHz): In the first stage a preliminary measurement will be performed in a shielded room with a measuring distance of 3 meters. Tabletop devices will set up on a non-conducting support with a size of 1 m by 1.5 m and a height of 8. Floor-standing devices will be placed directly on the turntable/ground plane. The set up of the Equipment under test will be in accordance to NSI C [1]. The frequency range 9 khz to 3 MHz will be monitored with a spectrum analyser while the system and its cables will be manipulated to find out the configuration with the maximum emission levels if applicable. The EMI Receiver will be set to MX Hold mode. The EUT and the measuring antenna will be rotated around their vertical axis to found the maximum emissions. The resolution bandwidth of the spectrum analyser will be set to the following s: range Resolution bandwidth 9 khz to 15 khz Hz 15 khz to 3 MHz khz 3 m EUT 1 m.8 m EMI receiver Examiner: Thomas KÜHN Date of issue: 24 November 9 Page 39 of 114

Final measurement (9 khz to 3 MHz): In the second stage a final measurement will be performed on an open area test site with no conducting ground plane in a measuring distances of 3 m, m and 3 m. In the case where larger measuring distances are required the results will be extrapolated based on the s measured on the closer distances according to Section (f) (2) [2]. The final measurement will be performed with a EMI Receiver set to Quasi Peak detector except for the frequency bands 9 khz to 9 khz and 1 khz to 49 khz where an average detector will be used according Section 15.9 (d) [2]. On the during the preliminary measurement detected frequencies the final measurement will be performed while rotating the EUT and the measuring antenna in the range of to 36 around their vertical axis until the maximum is found.

Tabletop devices will set up on a non-conducting support with a size of 1 m by 1.5 m and a height of 8. Floor-standing devices will be placed directly on the turntable/ground plane. The set up of the Equipment under test will be in accordance to NSI C [1]. The frequency range 3 MHz to 1 will be measured with an EMI Receiver set to MX Hold mode and a resolution bandwidth of khz. The measurement will be performed in horizontal and vertical polarisation of the measuring antenna and while rotating the EUT in its vertical axis in the range of to 36.
