Customer is getting very upset.. Les -----Original Message----- From: Compliance Certification Services [<mailto:[email protected]>mailto:[email protected]] Sent: Tuesday, July 22, 2003 2:35 PM Subject: TPL COMMUNICATIONS, FCC ID: BBD6-1AE, Assessment NO.: AN03T3040 (#2) 1. FCC rule para 2.925 requires the words "FCC ID" to be placed before the FCC identifier. Please submit revised label drawings or photographs that show compliance with this requirement. See attached label 2. The product interior photographs do not seem to have sufficient resolution. Please re-submit or re-scan at a higher resolution. New photos submitted jpg format 3. Will the amplifier be sold for use with 12.5 kHz channel bandwidth equipment? If so, the limit for emissions removed by more than 12.5 kHz must be suppressed by at least 50+10log(Pwatts). i.e., they must be less than -20dBm . The display line shown on the spuruios emissions graphs is -13 dBm. Please comment. New data sheet provided, please replace pages 53, 54 and 55 with new 53 and 54. 4. For spurious emission field strength emissions required by rule para. 2.1053, emissions are referenced to the radiated output power of the transmitter, assuming all emissions are radiated from a dipole. FCC interprets this to mean that the "substitution" method must be used to determine compliance. This method called out by EIA/TIA 603 specification (among others) requires that once radiated emissions from the EUT have been measured, the EUT is removed and a signal generator and substitution antenna is put in its place. Emissions are again maximized, the signal generator is set to match the radiated reading, and the resultant ERP is compared against the limit. Please submit data for radiated emissions performed in this fashion.Ê Submitted same as Item 3 5. Please submit a photograph showing the radiated emissions test set-upTypical Set up phots submitted The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 60 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted.

Also, based on the results of the enclosed data, I have concluded that the equipment tested meets or exceeds the requirements of the Rules and Regulations governing this application. 1.2 Measurement Repeatability Information The test data presented in this report has been acquired using the guidelines set forth in FCC Part 2.1031 through 2.1057, and Part 90. The test results presented in this document are valid only for the equipment identified herein under the test conditions described. Repeatability of these test results will only be achieved with identical measurement conditions. These conditions include: The same test distance, EUT Height, Measurement Site Characteristics, and the same EUT System Components. The system must have the same Interconnecting Cables arranged in identical placement to that in the test set-up, with the system and/or EUT functioning in the identical mode of operation (i.e. software and so on) as on the date of the test. Any deviation from the test conditions and the environment on the date of the test may result in measurement repeatability difficulties. All changes made to the EUT during the course of testing as identified in this test report must be incorporated into the EUT or identical models to ensure compliance with the FCC regulations. C. L.

FCC ID: BBD6-1AE 53 2.1053 Field Strength of Spurious Radiation Definition: Emissions from the equipment when connected into a non-radiating load on a frequency or frequencies which are outside an occupied band sufficient to ensure transmission of information of required quality for the class of communication desired. The reduction in the level of these spurious emissions will not affect the quality of the information being transmitted. Test Method: Per TIA /EIA 603. Connect the equipment and follow the procedure described in paragraph 2.2.1.1 and paragraph 5.0. Measure the amplitude of each spurious radiated signal through the 10 th harmonic. The spurious signals are then measured on the 3 meter range. First the EUT is measured using a tuned reference dipole below 1GHz and a double ridge guide Horn antenna above 1GHz. If the DRG antenna is used the appropriate gain factor for the antenna is subtracted from the final measurement. Then a dipole to dipole (or drg to drg) measurement is conducted to determine the actual power at each harmonic being generated by the EUT. If no noticeable emission can be observed the ground floor is recorded in the data sheets. Test Results: All readings were at the spectrum analyzer ground floor above the fundamental. All radiated spurious emissions are below the FCC Specifications.
