Technical Description of the Circuit: The product can divide into two part, RF and Baseband, the RF circuit is a single conversion, super-heterodyne architecture receiver IC. The incoming RF signal received by the antenna is fed to the RF input terminal of the IC RX3310A, then the RF signal is then amplified by the LNA in the IC RX3310A. The amplified signal will fed to the mixer input, the LO for the mixer is generated by the external LC tank circuit, in the above circuit, the LO is 433.12MHz, the IF (F RF -F LO ) is then demodulated by the demodulator in the IC RX3310A and the IC RX 3310A provide the raw data. The data is then fed to the baseband MCU TM8726 for decoding and the MCU TM8726 will display the decoded temperature at the LCD.

Brand Name: Nil Model Number: 260NU Rating:3.0Vd.c. ( 3 x “ AA” size batteries ) No. of Channel:1 Accessories and Auxiliary Equipment:None EUT Exercising Software:None Description of EUT The Equipment Under Test (EUT) is the wireless weather station operated at 433.920MHz to receive the temperature and humidity signal from the associated transmitter. As per Client Declaration, circuit design, PCB Layout, shielding and interface of 260NU, 260NC, 260BC and 260BU are identical, only the cosmetic is different. So, 260NU is selected to be a representative model to perform all testing. 1.4 Related Submittal(s) Grants This is a single application for certification of the receiver.

Unit 601, InnoCentre, 72 Tat Chee Avenue, Kowloon Tong, Hong Kong 3.0 Test Methodology 3.1 Radiated Emission The sample was placed 0.8m above the ground plane on a standard emission test site *. Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *On a standard emission test site with a metal ground plane filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90656. 3.2 Field Strength Calculation The field strength at 3 m was established by adding the meter reading of the spectrum analyzer to the factors associated with antenna correction factor, cable loss, preamplifiers and filter attenuation. The equation is expressed as follow: FS = R + System Factor System Factor = AF + CF + FA – PA Where FS = Net Field Strength in dBuV/m at 3 meters. R = Reading of Spectrum Analyzer / Test Receiver in dBuV. AF = Antenna Factor in dB. CF = Cable Attenuation Factor in dB. FA = Filter Attenuation Factor in dB. PA = Preamplifier Factor in dB. FA and PA are only be used for the measuring frequency above 1 GHz. 3.3 Conducted Emissions The EUT was placed on a non-metallic table 0.8m above the horizontal metal reference place and 0.4m from a vertical ground plane which is connected to the horizontal metal ground plane. Meanwhile, the AC main of EUT was connected to the distance of 0.8m line impedance stabilization network (LISN) during measurement. Initial measurements were performed in quasi-peak and average detection modes by the test receiver, any emissions recorded within 30dB of the relevant limit lines were re-measured using quasi-peak and average detection on the live and neutral lines with the worst case recorded in the table of results…
