19 Nemko-CCL, nc. TEST REPORT: ~2.1 Page 17 of Sample Field Strength Calculation: The field strength is calculated by adding the Correction Factor (Antenna Factor + Cable Factor), to the measured level from the receiver. The receiver amplitude reading is compensated for any amplifier gain. The basic equation with a sample calculation is shown below: FS = RA + CF Where FS = Field Strength RA = Receiver Amplitude Reading (Receiver Reading - Amplifier Gain) CF = Correction Factor (Antenna Factor + Cable Factor) Assume a receiver reading of 42.5 db/l V is obtained from the receiver, an amplifier gain of26.5 db and a correction factor of8.5 db/m. The field strength is calculat~d by subtracting the amplifier gain and adding the correction factor, giving a field strength of24.5 db/lv/m, FS = ( ) +8.5 = 24.5 db/lv/m.

20 Nemko-CCL, nc. Page 18 of31 APPENDX 1 TEST PROCEDURES AND TEST EQUPMENT A1.l Conducted Disturbance at Mains Ports: The conducted disturbance at mains ports from the EUT was measured using a spectrum analyzer with a quasi-peak adapter for peak, quasi-peak and average readings. The quasi-peak adapter uses a bandwidth of 9 khz, with the spectrum analyzer's resolution bandwidth set at 100 khz, for readings in the 150 khz to 30 MHz frequency ranges. The conducted disturbance at mains ports measurements are performed in a screen room using a (50 Q/50 ph) Line mpedance Stabilization Network (LSN). Where mains flexible power cords are longer than 1 m, the excess cable is folded back and forth as far as possible so as to form a bundle not exceeding 0.4 m in length. Where the EUT is a collection of devices with each device having its own power cord, the point of connection for the LSN is determined from the following rules: (a) Each power cord, which is terminated in a mains supply plug, shall be tested separately. (b) Power cords, which are not specified by the manufacturer to be connected via a host unit, shall be tested separately. (c) Power cords which are specified by the manufacturer to be connected via a host unit or other power supplying equipment shall be connected to that host unit and the power cords of that host unit connected to the LSN and tested. (d) Where a special connection is specified, the necessary hardware to effect the connection is supplied by the manufacturer for the testing purpose. ( e) When testing equipment with multiple mains cords, those cords not under test are connected to an artificial mains network (AMN) different than the AMN used for the mains cord under test. For AC mains port testing, desktop EUT are placed on a non-conducting table at least 0.8 meters from the metallic floor and placed 40 cm from the vertical coupling plane (copper plating in the wall behind EUT table). Floor standing equipment is placed directly on the earth grounded floor. Type of Equipment Manufacturer Model Number Serial Number Date of Last Calibration Wanship Open Area Test Nemko-CCL, nc.

22 Nemko-CCL, nc. Page 20 of31 A1.2 Radiated Disturbance: The radiated disturbance from the EUT was measured using a spectrum analyzer with a quasi-peak adapter for peak and quasi-peak readings. Apreamplifier with a fixed gain of 26 db and a power amplifier with a fixed gain of 22 db were used to increase the sensitivity of the measuring instrumentation. The quasi-peak adapter uses a bandwidth of 120 khz, with the spectrum analyzer's resolution bandwidth set at 1 MHz, for readings in the 30 to 1000 MHz frequency ranges. A biconilog antenna was used to measure the frequency range of 30 to 1000 MHz, at a' distance of 10 meters from the EUT. The readings obtained by these antennas are correlated to the levels obtained with a tuned dipole antenna by adding antenna factors. A double-ridged guide antenna was used to measure the emissions at frequencies above 1000 MHz at a distance of 3 and/or 1 meter from the EUT. The configuration of the EUT was varied to find the maximum radiated emission. The EUT was connected to the peripherals listed in Section 2.3 via the interconnecting cables listed in Section 2.4. A technician manually manipulated these interconnecting cables to obtain worstcase radiated disturbance. The EUT was rotated 360 degrees, and the antenna height was varied from 1 to 4 meters to find the maximum radiated emission. Where there were multiple interface ports all ofthe same type, cables are either placed on all of the ports or cables added to these ports until the emissions do not increase by more than 2 db. Desktop EUT are measured on a non-conducting table 0.8 meters above the ground plane. The table is placed on a turntable, which is level with the ground plane. For equipment normally placed on floors, the equipment shall be placed directly on the turntable.
