PVCGTP212Audio Video Transmitter

FCC ID: PVCGTP212 A1: The Block diagram for transmitter has submitted. A2: All models’ PCB are the same and only for different customers. A3: Internal photographs of transmitter module has submitted. A4: The form 731 has corrected and submitted. A5: The users manual has corrected and submitted. A6: Because the unwanted emission will fail if the output power yields 97 dBV/m, so the client decreased the output power by external components. A7: The user manual has been corrected and submitted. A8: Corrected as submitted document. A9: Peak: RBW=1M, VBM=1M; Average: RBW=1M, VBW=10Hz A10: Corrected as attachment. A11: RBW=1M; VBM=1M Training Research Co., Ltd. Jacob Lin

Timothy : (1) Yes, they put a bypass capacitor on the ANT output which is located near the ANT connection on the main PCB. (2) I think you can see the component by internal photo. Maybe it is too small. (3)(4) I will do it after you can understand my explanation for (1) (2) . Wait for your further information ,Thanks ! Jacob Lin ----- Original Message ----- From: Timothy R. Johnson <[email protected]> To: Jacob <[email protected]> Sent: Friday, July 05, 2002 1:49 PM Subject: Re: Review of Grandtec Electronic Corp., FCC ID: PVCGTP212 Jacob, Thank you for your reply. Most of the information is resolved. However, I do not understand what your response to Question 6) means: "A6: Because the unwanted emission will fail if the output power yields 97 dBìV/m, so the client decreased the output power by external components." 1) Does this mean that modifications were required to pass? Yes or No. Please try and explain what was done. 2) Where are the external components you mentioned? The RF is a OEM module. I did not see any components after the Antenna output from the module. If there are components here, then this should be shown. 3) Please provide a higher resolution page 2 schematic. The one provided is not clear enough. 4) Also, the corrected pages to the test report were uploaded with the confidentiality checked. Please note that we can not hold test report information as confidential. Thanks, Tim To: "Timothy R. Johnson" <[email protected]> Subject: Re: Review of Grandtec Electronic Corp., FCC ID: PVCGTP212 Page 1 of 1Grandtec Elect PVCGTP212 7/14/2002Printed for "Timothy R. Johnson" <[email protected]>

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 30, 2002 RE: Grandtec Electronic Corp. FCC ID: PVCGTP212 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The block diagram provided is for the receiver. Please provide a block diagram for the transmitter. 2) Several model numbers are listed throughout the application. Please explain the differences between each of these models and also provide the justification made for which one was selected for testing. 3) Please provide internal photographs of the RF portion of the product with the shield removed. Since the RF section of this product is a separate component, please be sure to provide top and bottom photographs of the component as well. 4) The Form 731 should state the actual frequency tuning/transmission range of the device. Please adjust section 6 of the 731 form to state 2410-2470 MHz. 5) FYI, for products certified under 15.249, RF exposure information is not required. a) The users manual contains RF exposure information on the bottom of page 2. Please remove the section (3) contained at the bottom of page 2 in the users manual regarding RF Exposure information. b) We will ignore the RF Exposure exhibit provided. 6) An output of 1 dBm with a 1 dBi gain antenna should yield a field strength at 3 meters of around 97 dBuV/m (the limit is 94 dBuV). However the maximum reading obtained was 86 dBuV/m, which is about 10 dB lower than expected. Please explain this discrepancy. 7) The test report (page 6 of 30) states a TX power of 1 dBm, while the Users Manual (page 5 of 13) states 10 dBm. Given a 1/4 wave dipole and a limit of 94 dBuV/m @ 3 meters, the output power would have to be under 1 dBm. Please correct affected exhibits. 8) Please update section 1.6 of the test report to include information for the OAT's site used for < 1 GHz. testing. 9) Please confirm both the RBW & VBW settings used for peak and average radiated measurements above 1 GHz. 10) Please correct the tables on pages 20, 22, 23, & 24 of the test report to show the raw readings and the correction factors applied. 11) Please provide the RBW and VBW settings used for Appendix B. Also, please provide a calculation for this data showing compliance with 15.209. Timothy R.

Complete description and measurement data have been placed on file with the commission. The conducted power line emissions tests and other test items were performed in a anechoic chamber also located at Training Research Co., Ltd. 1F, No. 2, Lane 194, Huan-Ho Street, Hsichih, Taipei Hsien 221, Taiwan, R.O.C. Training Research Co., Ltd. is listed by the FCC as a facility available to do measurement work for others on a contract basis. 1.7 General Test Condition The conditions under which the EUT operates were varied to determine their effect on the equipment's emission characteristics. The final configuration of the test system and the mode of operation used during these tests were chosen as that which produced the highest emission levels. However, only those conditions, which the EUT was considered likely to encounter in normal use were investigated. In test, the base and handset are tested separately. They were set in Ch1, Ch3 and Ch4 of EUT and continuously transmitting mode that controlled by test mode of EUT.
