Test Method: FCC part 2.1053 TIA-603-E-2016 EUT Operation: Status: Drive the EUT to maximum output power. Conditions: Normal conditions Application: Enclosure Test Configuration: 9 kHz to 30 MHz emissions: SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Report No.: SZEM200500399601 Page: 93 of 165 30MHz to 1GHz emissions: 1GHz to 40GHz emissions: SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Report No.: SZEM200500399601 Page: 94 of 165 Test Procedure: 1. Test the background noise level with all the test facilities; 2. Keep one transmitting path, all other connectors shall be connected by normal power or RF leads; 3. Select the suitable RF notch filter to avoid the test receiver or spectrum analyzer produce unwanted spurious emissions; 4. Keep the EUT continuously transmitting in max power; 5. Read the radiated emissioins of the EUT enclosure. Radiated Emissions Test Procedure: a) Connect the equipment as illustrated. b) Adjust the spectrum analyzer for the following settings: 1) Resolution Bandwidth = 100 kHz for spurious emissions below 1 GHz, and 1 MHz for spurious emissions above 1GHz. 2) Video Bandwidth = 300 kHz for spurious emissions below 1 GHz, and 3 MHz for spurious emissions above 1 GHz. 3) Sweep Speed slow enough to maintain measurement calibration. 4) Detector Mode = Positive Peak. c) Place the transmitter to be tested on the turntable in the standard test site, The transmitter is transmitting into a nonradiating load that is placed on the turntable. The RF cable to this load should be of minimum length. d) Measurements shall be made from30MHz to 10 tims of fundamental carrier, except for the region close to the carrier equal to ± the carrier bandwidth. e) Key the transmitter without modulation or normal modulation base the standard. f) 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. Then the turntable should be rotated 360° to determine the maximum reading. Repeat this procedure to obtain the highest possible reading. Record this maximum reading. g) Repeat step f) for each spurious frequency with the test antenna polarized vertically. SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Report No.: SZEM200500399601 Page: 95 of 165 h) Reconnect the equipment as illustrated. i) Keep the spectrum analyzer adjusted as in step b). j) 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 the 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. k) Feed the substitution antenna at the transmitter end with a signal generator connected to the antenna by means of a nonradiating 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. l) Repeat step k) with both antennas vertically polarized for each spurious frequency. m) Calculate power in dBm into a reference ideal half-wave dipole antenna by reducing the readings obtained in steps k) and l) 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 by the following formula: Pd(dBm) = Pg(dBm) – cable loss (dB) + antenna gain (dB) where: Pd is the dipole equivalent power and Pg is the generator output power into the substitution antenna. NOTE: It is permissible to use other antennas provided they can be referenced to a dipole. NOTE: Effective radiated power (e.r.p) refers to the radiation of a half wave tuned dipole instead of an isotropic antenna. There is a constant difference of 2.15 dB between e.i.r.p. and e.r.p. e.r.p (dBm) = e.i.r.p. (dBm) – 2.15 SGS-CSTC Standards Technical Services Co., Ltd.
