Timco Engineering Inc. 849 NW State Road 45 Newberry FL 32669 Page 1 of 4 From: Mario de Aranzeta [email protected] To: Stan Lyles [email protected] FCC Application Processing Branch Re: FCC ID L9N-7085-UE Applicant: AES Corporation Correspondence Reference Number: 22487 731 Confirmation Number: EA557675 1.) Please provide the modulation limiting test data using a input signal of 4800 Hz. This is the minimum data rate allowed Per Section 90.203(j)(3) in order to meet the spectrum efficiency standard. Enclosed on page 4 is the modulation limiting plot. 2.) Please recalculate your emission designator for question number 1. Page 2 is a revised test report page that corrects the emission designator. 3.) Your test report indicates an F3E (Voice) mode is available, however there is no indication that the device transmitter information other than data. Please clarify. Page 2 also contains the revised test report page that eliminates the erroneous F3E designator. 4.) Please provide the dBm power levels on page 16 of the radiated spurious emissions measurements. Our test method for the substitutio n method is as described in TIA/EIA 603 (2.2.12) using a dipo le for frequencies below 2.4 GHz. Above 2.4 GHz a do uble ridged antenna is used and referenced back to a dipole. A signal generator capable of 10 Watts of output power is used below 1GHz. We don’t usually keep the dBm power levels info so I’ve had to remeasured it and submitted it as page 3. Some of the dBc numbers wo n’t be exactly the same as the test report. If this information is something we need to include in future reports please let me know so we can preserve and report this information.
