American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 22, 2002 RE: FCC ID: PVCGTP224 Attention: Jack Tsai I have a few comments on this Application. 1 The Bi-log Antenna (CBL6141A from Schaffner) serial # 4206 shows that it was out of cal when the test was performed. The Antenna is listed as having to be calibrated by 03/09/02, yet the test was performed 5/14/02. Section 3.1 shows that this antenna was used for the test. Please provide a test report with properly calibrated test equipment. xx 2 Section 3.1 of the report says that the final radiated emissions was done in an anechoic chamber. The test setup photos and the table in section 3.4 of the report say it was done on an OATS. Please correct the report to be consistent for OATS testing. xx 3 Because item one is out of calibration, the following becomes a concern. The Tx chip in the device is listed as a 10mW device (10dBm). This being the case, assuming the 10mW was delivered to the antenna terminal and with a 1.26 gain antenna the dBuV level at 3 meters would be approximately 100+dBuV. The report states that the highest measured reading was 77+ dBuV at 3 meters. Please clarify the actual power rating of the chip Tx power and please verify, using calibrated antenna(s), what the field strength is at 3 meters is. This request is in conjunction with item 1 above. xx 4 The RF exposure calculations are used to estimate the closest range the device can operate to a person so a claim of compliance to 1.1307 can be made. The RF exposure statement you provided only uses the field strength, gain and distance to calculate the value of S. This does not provide the distance factor necessary to make a claim of categorical exclusion as specified in 1.1306. Please correct this RF exposure statement to provide the minimum distance the device is allowed to be to the person by which categorical exclusion is made. xx 5 Also, please note that this distance statement provided categorical exclusion needs to be in the manual. A statement similar to “The antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.” Is sufficient. xx 6 Please note that since there is no request for confidentiality, no part of this application will be held confidential. If confidentiality is requested, please provide a letter requesting confidentiality under 0.457 and 0.459 of CFR47. If confidentiality is requested please specify which parts are confidential. Only schematics, theory of operations and block diagrams are typically held confidential. xx Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued.

Test Report ----------------------------------------------------------------------------- 16/33 Report No.: GA215146, FCC Part 15 Class B Training Research Co., Ltd., TEL:886-2-26935155, Fax:886-2-26934440 . Radiated Emissions Measurements 3.1 Test Condition & Setup The EUT was placed in an anechoic chamber and scanned at 3-meter distance to determine its emission characteristics. The physical arrangement of the EUT was varied (within the scope of arrangements likely to be encountered in actual use) to determine the effect on the unit's emanations in amplitude, directivity, and frequency. The exact system configuration, which produced the highest emission was noted so it could be reproduced later during the final tests. This was done to ensure that the final measurements would demonstrate the worst-case interference potential of the EUT. Final radiation measurement (frequency above 1GHz) was made in a three-meter anechoic chamber. The frequency below 1GHz was made in a three-meter OATS. The EUT system was placed on a nonconductive turntable, which is 0.8 meters height, top surface 1.0 x 1.5 meter. The spectrum was examined from 30MHz to 1000MHz using an Hewlett Packard 8546A & 85460A EMI Receiver, Schaffner whole range Bi-Log antenna (Model No.: CBL6141A) is used to measure frequency from 30 MHz to 1GHz.The final test is used the spectrum HP 8546A & 85460A and spectrum was examined from 1GHz to 24GHz using an Hewlett Packard 8564E Spectrum Analyzer, EMCO Horn Antenna for 1G to 24 G Hz. At each frequency, the EUT was rotated 360 degrees, and the antenna was raised and lowered from one to four meters to find the maximum emission levels. Measurements were taken using both horizontal and vertical antenna polarization. Appropriate preamplifiers were used for improving sensitivity and precautions were taken to avoid overloading or desensitizing the spectrum analyzer. There are two spectrum analyzers use on this testing, HP 8546A & 85460A for frequency 30MHz to 1000MHz, and 8564E for frequency 1GHz to 24GHz. No post-detector video filters were used in the test. The spectrum analyzer's was set in the quasi-peak mode. (spectrum was examined from 30MHz to 1000MHz), the spectrum analyzer's bandwidth was set to 1MHz (spectrum was examined from 1GHz to 24GHz) and the analyzer was operated in the peak and average mode. The actual field intensity in decibels referenced to 1 microvolt per meter (dBV/m) is determined by algebraically adding the measured reading in dBV, the antenna factor (dB), and cable loss (dB) at the appropriate frequency.
