Item 6: The plots submitted were made at the lowest channel (Channel 1) and highest channel (Channel 20). Please refer to the attached “Frequency Table”. It looks like the center frequency shifted 500 kHz away from the band edge. I think it is the way it was designed. If the plots are not clear, we will resubmit it. Item 7: The power test and power density test were done as follows: 1.We disconnected the antenna from the EUT. 2.We connected the RF output directly to the input of the spectrum analyzer thru a low loss cable. We think this method will give us a better control and more accurate reading. Should you need more or have any questions, please contact the undersigned. Sincerely, Xi-Ming Yang Test Engineer A

Processing Gain Measurements for MH9027 DCT TEST report 1. Introduction 1.1 Scope This document is a ISV Engineering test report for MH9027 basic DCT cordlessphone. This document details the results of measurement of the processing gain of a DCT FFF phone. 1.2 Reference Documents This section lists documents that are referenced within or are materially relevant to this document. Code of Federal Regulations, Title 47, Chapter 1, Part 15 Radio Frequency Devices (FCC) 1.3 Definitions FCCFederal Communications Commission SNRSignal to Noise Ratio JSRJammer to Signal Ratio CWContinuous wave (jammer) HSHandset BSBasestation DBPSKDifferential Binary Phase Shift Keying Table 1: Definitions and Abbreviations 2. An Overview of the FCC Method for measuring Processing Gain Two methods are specified for measuring processing gain by the FCC in 15.247 (e). The first method simply involves calculating the signal to ratio noise (SNR) with the spreading code switched on with the SNR when the spreading code is switched off. The difference between the two is the processing gain. The SNR is measured at the demodulated output of the receiver. In principle this an acceptable method to measure the processing gain of any direct sequence spread spectrum communication system, however, it does not take into consideration that the non-spread spectrum portion of the system may operate under the assumption that the signal being transmitted is a spread spectrum signal and when the spreading code is switched off the system may fail to operate or operate at greatly reduced efficiency, In either case the measurement of processing gain will be meaningless. The second method specified by the FCC to measure processing gain is detailed in 15.247 (e)(1). This involves transmitting a CW jammer in the RF passband of the system and measuring the jammer to signal ratio (JSR) required to achieve a certain bit error rate. The choice of the actual value of the bit error rate is left up to the tester. The jammer is stepped in 50 kHz increments across the entire passband and in each case the JSR to achieve the desired bit error rate is measured. The JSR is measured at the RF input to the system under test. The lowest 20% of the JSR data (in dB) is discarded. The processing gain can then be calculated as follows:- system measuredtheory p L S J N S G+ ö ç è æ + ÷ ö ç è æ = where G p is the processing gain, the SNR is that theoretically predicted for the system under the test to achieve the desired bit error rate, the JSR is the lowest value (in dB) in the remaining data set and L sys adjusts for non-ideal system losses. L sys can not be greater than 2 dB. 3. Processing Gain Measurement Results The following parameters were used in the test setup. HS Tx power (dBm)-4.3 BS LNA gain (dB)0 Test system losses (signal) (dB) -14.55-4.05 dB (system), -3 dB (signal combiner), -7.5 dB (2 cables) Test system losses (jammer) (dB) -5.6-3 dB (signal combiner), -2.6 dB (2cables) Table 2: Test Setup Parameters The following measurement results were taken at the basestation.
