Operating Description of Receiver The received signal of 311MHZ from C1 is amplified by Q2 which is 1st. RF amplifier and C3 is output of this amplifier. This signal is supplied to Q3 circuits. The Q3 circuits is Local Oscillator, Mixer and Detector. The detected signal is come out from L2 and amplified 300 times by OP AMP U1A at first and amplified by U1B at pin No. 2. The final amplified detected signal is come out from pin No.1 of U1B.

RADIATED EMISSION MEASUREMENT (Section 15.109) 1. Test Procedure 1.1 Preliminary Testing for Reference Preliminary testing was performed in a KTL absorber-lined room to determine the emission characteristics of the EUT. The EUT was placed on the wooden table which has dimensions of 0.8 meters in height, 1 meter in length and 1.5 meters in width. Receiving antenna (Biconical antenna : 30 to 300MHz, Log-periodic antenna : 200 to 1000MHz or Horn Antenna : 1 to 18GHz) was placed at the distance of 1 meter from the EUT. In order to cohere the individual components of the characteristic broadband emission from the receiver(EUT), a RF generator(CW signal) and a log-periodic antenna were used. The frequency and output level of the generator were adjusted for highest observed coherent receiver emissions on the spectrum analyzer with RF amplifier. An attempt was made to maximize the emission level with the various configurations of the EUT. The effect of changing the position of the cable was observed to find the worst case configuration while rotating the table and varying antenna height and it’s polarization. Radiated and spurious emissions were checked from 30 MHz to 3000 MHz according to section 15.33. 1.2 Final Radiated Emission Test at an Absorber-Lined Room The final measurement of radiated field strength was carried out in a KTL Absorber-Lined Room that was listed up at FCC according to the "Radiated Emissions Testing" procedure specified by ANSI C63.4. Based on the test results in preliminary test, measurement was made in same test set up and configuration which produced maximum emission level. Receiving antenna was installed at 3-meter distance from the EUT, and was connected to an EMI receiver or spectrum analyzer(for above 1GHz) with a RF amplifier. Turntable was rotated through 360 degrees and receiving antenna height was varied from 1 to 4 meters above the ground plane to read maximum emission level. The maximum emission level from the EUT occurred i…

Sample Calculation The emission level measured in decibels above one microvolt (dB) was converted into microvolt per meter (/m) as shown in following sample calculation. For example : Measured Value at 312.0 MHz 37.9 dB + Antenna Factor 14.0 dB/m + Cable Loss 3.3 dB - Preamplifier 30.0 dB - Distance Correction Factor * 0.0 dB ------------------------------------------------------------------------------------------- = Radiated Emission 25.2 dB/m ( = 18.2 /m ) * Extrapolated from the measured distance to the specified distance by an inverse linear distance extrapolation.
