A-030-01-C Page 7 of 24 3.3 Test Procedure (1) Tune-up the transmitter. (2) The receiving antenna is adjusted to the correct length for the carrier frequency. (3) Raise and lower the receiving antenna to obtain a maximum reading on the Spectrum Analyzer with the antenna at horizontal polarity. Then the turntable is rotated to further increase this maximum reading. Repeat this procedure of raising and lower the antenna and rotating the turntable until the highest possible signal has been obtain. Record this maximum reading. (4) Repeat step3 with the antenna polarized vertically. (5) Remove the transmitter and replace it with the half-wave antenna. The center of these antennas are approximately at the same location as the center of the transmitter. (6) Feed the half-wave 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 the carrier frequency, raise and lower the receiver antenna to obtain a maximum reading at the Spectrum Analyzer. Adjust the level of the signal generator output until the previous recording maximum reading for this set of conditions its obtained. (7) Repeat step6 with both antennas vertically polarized.

A-030-01-C Page 12 of 24 5.3 Test Results See next figure (the picture of spectrum analyzer) Occupied Bandwidth I have measured the OBW by the spectrum analyzer R3261B which could measure 99% occupied bandwidth (OBW). There are 701 data on horizontal axis of display. One of them is Vn. Then total power P can be calculated from the following formula. 701 2 P=∑ Vn (1) n =1 R where, R is input impedance of R3261B. Let, x is the point which gives 0.5% of the total power and y is the point which gives 99.5% of the total power. Then we can get the following formula. 2 x 0.005P = ∑ Vn (2) n =1 R y 2 0.995P = ∑ Vn n =1 R (3) From(1)- (3), OBW becomes . Fspan(Y − X ) OBW = 1000 where, Fspan is frequency span of the spectrum analyzer. KEC Ikoma Testing Laboratory 12128 Takayama-cho Ikoma-city Nara 630-0101 Japan

FIELD STRENGTH OF SPURIOUS RADIATION 6.1 Reference Rule and Specification FCC Rule Part 95 [Section 95.635] and Part 2 Subpart J [Section 2.1053] 6.2 Test Procedure (1) Tune-up the transmitter(EUT). (2) Device Vertical : Place the device so that it's longest axis is vertical. (3) For each spurious measurement the receiving antenna is adjusted to the correct length for the frequency involved. These measurements are made from the lowest radio frequency generated in the EUT or 25MHz to the tenth harmonic of the carrier. (4) For each spurious frequency, raise and lower the receiving antenna to obtain a maximum reading on the spectrum analyzer with the antenna at horizontal polarity. Then the turntable is rotated to further increase this maximum reading. Repeat this procedure of raising and lower the antenna and rotating the turntable until highest possible signal has been obtain. Record this maximum reading. (5) Repeat Step4 for each spurious frequency with the antennae polarized vertically. (6) Device Horizontal : Place the device so that it's longest axis is horizontal. (7) Repeat Step3, Step4, and Step5 (8) The attenuation of the spurious in dB can be calculated from the following formula: Spurious Emission Field Strength Field Strength Attenuation = of Carrier Emission − of Spurious Emission [dB] [dBµV/m] [dBµV/m] KEC Ikoma Testing Laboratory 12128 Takayama-cho Ikoma-city Nara 630-0101 Japan
