Conducted Spurious Emissions Name of Test: Conducted Spurious Emissions Engineer: Alex Macon Test Equipment Utilized: i00124, i00331, i00432 Test Date: 6/2/15 Test Procedure The EUT was connected directly to a spectrum analyzer to verify that the UUT met the requirements for spurious emissions. A tunable notch filter was utilized to ensure the fundamental did not put the spectrum analyzer into compression. The resolution bandwidth set for 100 kHz and the reference level was adjusted to ensure the system had th sufficient dynamic range to measure spurious emissions. The frequency range from 30 MHz to the 10 harmonic of the fundamental transmitter was observed and plotted. The limit line was set for -25 dBm for comparison to RSS-119 which is the more stringent limit.

Field Strength of Spurious Radiation Name of Test: Field Strength of Spurious Radiation Engineer: Paul Hau Test Equipment Utilized: i00103, i00349, i00379, i00428 Test Date: 6/5/15 Test Procedure A) Connect the equipment as illustrated below. B) Adjust the spectrum analyzer to the following settings: 1) Resolution Bandwidth 100 kHz (< 1 GHZ), 1 MHZ (> 1GHz) 2) Video Bandwidth ≥ 3 times Resolution Bandwidth, or 30 kHz 3) Sweep Speed ≤2000 Hz/second 4) Detector Mode = Mean or Average Power C) Place the transmitter to be tested on the turntable in the standard test site. The transmitter is transmitting into a non- radiating load that is placed on the turntable. The RF cable to this load should be of minimum length. D) For each spurious measurement the test antenna should be adjusted to the correct length for the frequency involved. This length may be determined from a calibration ruler supplied with the equipment. Measurements shall be made from the lowest radio frequency generated in the equipment to the tenth harmonic of the carrier, except for the region close to the carrier equal to ± the test bandwidth (see Section 1.3.4.4). E) For each spurious frequency, raise and lower the test antenna from 1 m to 4 m to obtain a maximum reading on the spectrum analyzer with the test antenna at horizontal polarity. Repeat this procedure to obtain the highest possible reading. Record this maximum reading. F) Repeat Step E) for each spurious frequency with the test antenna polarized vertically. G) Reconnect the equipment as illustrated. H) Keep the spectrum analyzer adjusted as in Step B). I) Remove the transmitter and replace it with a substitution antenna (the antenna should be half wavelength for each frequency involved). The center of the substitution antenna should be approximately at the same location as the center of the transmitter. At lower frequencies, where the substitution antenna is very long, this will be impossible to achieve when the antenna is polarized vertically. In such case the lower end of the antenna should be 0.3 m above the ground. J) Feed the substitution antenna at the transmitter end with a signal generator connected to the antenna by means of a non-radiating cable. With the antennas at both ends horizontally polarized and with the signal generator tuned to a particular spurious frequency, raise and lower the test antenna to obtain a maximum reading at the spectrum analyzer. Adjust the level of the signal generator output until the previously recorded maximum reading for this set of conditions is obtained. This should be done carefully repeating the adjustment of the test antenna and generator output. K) Repeat Step J) with both antennas vertically polarized for each spurious frequency. L) Calculate power in dBm into a reference ideal half-wave dipole antenna by reducing the readings obtained in Steps J) and K) by the power loss in the cable between the generator and the antenna and further corrected for the gain of the substitution antenna used relative to an ideal half-wave dipole antenna. M) The levels recorded in Step L) are absolute levels of radiated spurious emissions in dBm. The radiated spurious emissions in dB can be calculated by the following: Radiated spurious emissions dB = 10log10 (TX power in watts/0.001) – the levels in Step I) NOTE: It is permissible that the other antennas provided can be referenced to a dipole. p1550009_FCC_Part 90_Rev 1.0 Page 10 of 25
