The output was connected to a spectrum analyzer with a RBW setting of 1 MHz and RMS detector activated. The spectrum analyzer was connected to an external 10 MHz reference standard during the measurements. Before comparing the results to the limit, 6 dB [10 log (4)] to cover 2x(2x2) MIMO, should be added according to method c “measure and add 10 log(NANT)” of FCC KDB662911 D01 Multiple Transmitter Output.

Remark The emission at 9 kHz on the plots was not generated by the test object. A complementary measurement with a smaller RBW showed that it was related to the LO feed-through. The highest fundamental frequency is 1990 MHz. The measurements were made up to 20 GHz (10x1990 MHz = 19900 MHz). Limits CFR 47 §24.238 and RSS-133 6.5 Outside a licensee's frequency band(s) of operation the power of any emission shall be attenuated below the transmitter power (P) by at least 43 + 10 log (P) dB, resulting in a limit of -13 dBm per 1 MHz RBW.

The test site complies with RSS-Gen, Industry Canada file no. 3482A-1. The measurements were performed with both horizontal and vertical polarization of the antenna. The antenna distance was 3 m in the frequency range 30 MHz – 18 GHz and 1 m in the frequency range 18 GHz – 20 GHz. RF absorbers were covering a floor area in the frequency range 1 GHz – 18 GHz to comply with site validation requirements according to ANSI C63.4-2014. The EUT was placed 0.8 m above reference ground plane in frequency range 30 MHz – 1 GHz and 1.5 m above reference ground plane in frequency range 1 GHz – 20 GHz. The measurement was performed with a RBW of 1 MHz. A propagation loss in free space was calculated. The used formula was  4 D  , is the propagation loss and is the antenna distance.   20 log    D    The measurement procedure was as the following: 1. A pre-measurement is performed with peak detector. For measurement < 1 GHz the test object was measured in eight directions with the antenna at three heights, 1.0 m, 1.5 m and 2.0 m. For measurements > 1 GHz the test object was measured in seventeen directions with the antenna height 1.0 m, 1.5 m and 2m. 2. Spurious radiation on frequencies closer than 20 dB to the limit in the pre-measurement is scanned 0-360 degrees and the antenna is scanned 1- 4 m for maximum response. The emission is then measured with the RMS detector and the RMS value is reported. Frequencies closer than 10 dB to the limit when measured with the RMS detector were measured with the substitution method according to ANSI 63.26. RISE Research Institutes of Sweden AB
