Processing Gain TEST REPORT Report No.: Z01C-02080 Issue Date: March 29, 2002 FCC CFR 47, Paragraph 15.247(e) Equipment under test : WIRELESS CONTROLLER & RECEIVER for VIDEOGAME FCC ID : EW4DOLAW Trade Name : NINTENDO GAMECUBE WIRELESS COTROLLER WAVEBIRD Model Number : DOL-004 ZACTA Technology Corporation Yonezawa Testing Center 4149-7 Hachimanpara 5-chome Yonezawa-shi Yamagata 992- 1128 Japan Phone: +81-238-28-2880 Fax: +81-238-28-2888 Scope This report contains the results of the processing gain testing performed on the "NINTENDO GAMECUBE WIRELESS CONTROLLER WAVEBIRD". The tests were carried out in accordance with FCC CFR 47 Part 15, Paragraph 15.247(e). The jamming margin method specified 15.247(e)(2) was used to perform the processing gain testing. FCC97-114, Guidance on Measurements for Direct Sequence Spread Spectrum Systems, was also utilized as a guiding document for performance of the processing gain testing. FCC Requirements The processing gain of direct sequence system shall be at least 10dB. The processing gain shall be determined from the ratio n dB of the signal-to-noise ratio with the system spreading code turned off to the signal-to-noise ratio with the system spreading code turned on, as measured at the demodulated output of the receiver. Test Equipment Agilent Signal Generator, MODEL 8648D, 9kHz-4GHz Anritsu Power Meter, MODEL ML2437A Anritsu Power Sensor, MODEL MA2472A, 10MHz-18GHz Anritsu Data Transmission Analyzer, MODEL MD6420A Anritsu 2-Way Combiner/Splitter, MODEL Z-164A Agilent Step Attenuator, MODEL 8494B/8496B, 1dB step/10dB step Method of Measurement As mentioned in the scope section, the jamming margin method was used. The following drawing titled "Processing Gain - Jamming Test Setup" illustrates a block diagram of the test setup. In this method, a signal generator was stepped in 50kHz increments across the passband of the system. At each point, the level of the signal generator required to produce the recommended Bit Error Rate (BER) was recorded. This level is the jammer level. The output power of the transmitter was also recorded at these same points. This level is the signal level. The jammer to signal ratio (J/S) was then calculated. The worst 20% of the J/S data points were discarded. The lowest remaining J/S ratio was used to calculate the processing gain for each of (S/N)o + Mj + Lsys, where Gp = the processing gain of the system, (S/N)o = signal to noise ratio required for the chosen BER, Mj = J/S ratio, and Lsys = system losses. Note that total system losses in a system, including intentional radiator and receiver, are assumed to be no more than 2dB as specified by the FCC. An ideal signal to noise ratio, also referred to as (S/N)o or (Es/No), of 13.3dB was used as specified by MegaChips when calculating the processing gain when operating at 96kbps. The "NINTENDO GAMECUBE WIRELESS CONTROLLER WAVEBIRD" operates at bit rates 96kbps only. A BER (bit error rate) of 1.0e-4 was used to calculate the processing gain. The data presented in this report is for the all case operation of the EUT.
