SYSTEM TEST CONFIGURATION 3.1 Justification The system was configured for testing in a typical fashion (as a customer would normally use it). Its antenna is on PCB. The EUT is for remote control and does not send data. The transmission does stop when the button is released after the completion of the frame. This time is than 5 seconds. Testing was performed as EUT was operated continuously. Fresh batteries were used. 3.2 Special Accessories N/A 3.3 Configuration of Tested System Figure 3.1 to Figure 3.5 illustrate this system, which is tested standing along. 9

CONDUCTED EMISSION DATA 5.1 Test Methods and Conditions The EUT was under normal operational mode during the conducted emission test. EMI Receiver was scanned from 150KHz to 30MHz with maximum hold mode for maximum emission. Recorded data was sent to the plotter to generate output in linear format. At the input of the spectrum analyzer, a HP transient limiter is inserted for protective purpose. This limiter has a 10 dB attenuation in the range of 150KHZ to 30MHZ. That factor was automatically compensated by the receiver, so the readings are the corrected readings. The reference of the plot is the CISPR 22 Class B limit in Figure 5.1 through Figure 5.2. Conducted Emission Technical Requirements Class A Class B Frequency Range Quasi-Peak Average Quasi-Peak Average dBuV dBuV DBuV dBuV 150kHz –0.5MHz 79 (8912uV) 66 (1995uV) 66-56 56-46 0.5MHz-30MHz 73 (4467uV) 60 (1000uV) --- --- 0.5MHz- 5MHz --- --- 56 46 (250uV) 5MHz-30MHz --- --- 60 50 Emissions that have peak values close to the specification limit (if any) are also measured in the quasi-peak mode to determine compliance. 5.2 Test Data Figure 5.1-5.2 show the neutral and line conducted emissions for the standard operation.

RADIATED EMISSION DATA 6.1 Field Strength Calculation The corrected field strength is automatically calculated by EMI Receiver using following: FS = RA +AF + CF + AG where FS: Corrected Field Strength in dB V/m RA: Amplitude of EMI Receiver before correction in dB V AF: Antenna Factor in dB/m CF: Cable Attenuation Factor in dB AG: Built-in Preamplifier Gain in dB (Stored in receiver as part of the calibration data) The pulse train timing plots are showed in Figure 6.2. The pulse train timing plots as follows: The total time for each pulse train is 139.62 ms, The short pulse is 0.640ms, The middle pulse is 2.5 ms, The long pulse is 4.8ms. Coeff. =(55x0.640+1x4.8+5x2.5)/100=0.525 The maximum average field strength should be 0.525 of the peak field strength measured. So we use peak value minus 5.6dB as calculated maximum average field strength. 6.2 Test Methods and Conditions The initial step in collecting radiated data is a EMI Receiver scan of the measurement range below 30MHz using peak detector and 9KHz IF bandwidth / 30KHz video bandwidth. For the range under 1GHz, 120KHz IF bandwidth / 120KHz video bandwidth are used. Both bandwidths are 1MHz for above 1GHz measurement. Up to 10th harmonics were investigated. 6.3 Test Data The following data lists the significant emission frequencies, polarity and position, peak reading of the EMI Receiver, the FCC limit, and the difference between the peak reading and the limit. Explanation of the correction and calculation are given in section 6.1. Test Personnel: Typed/Printed Name: Edward Lee Date: March 26, 2012 17
