Report number TA000647 Page 10 of 31 NAME OF TEST: Field Strength of Spurious Radiation SPECIFICATION: 47 CFR 2.1053 (a) GUIDE: ANSI/TIA/EIA-603, Paragraph 1.2.12 MEASUREMENT PROCEDURE 1.2.12.1Definition: Radiated spurious emissions are emissions from the equipment when transmitting load on a frequency or frequencies which are outside an occupied band sufficient to ensure transmission of information of required quality for the class of communications desired. 1.2.12.2Method of measurement A) Connect the equipment as illustrated. B) Adjust the spectrum analyzer for the following settings: 1) Resolution Bandwidth <= 3kHz 2) Video Bandwidth >= 10kHz 3) Sweep Speed <= 2000Hz/second 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 non-radiating load which is placed on the turntable. The RF cable to this load should be of minimum length. Test antenna STANDARD TRANSMITTER SPECTRUM TRANSMITTER UNDER TEST ANALYZER LOAD STANDARD TEST SITE D) For each spurious measurment the test antenna should be adjusted to the correct length for the frequency involved. This length maybe 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 qeual 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. Vertex Standard Co., Ltd.

Report number TA000647 Page 11 of 31 NAME OF TEST: Field Strength of Spurious Radiation F) Repeat step E) for each spurious frequency with the test antenna polarized vertically Substitution Test antenna antenna RF SIGNAL SPECTRUM GENERATOR ANALYZER STANDARD TEST SITE 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 substitutuion 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 plarized vertically In such case the lower end of the antenna should be 0.3m 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 untill the previusl recorded maximum reading for the 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 step J) and K) by the power loss in the cable between the generator and the antenna and futher 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 L) Vertex Standard Co., Ltd.
