List.pdf (7 KB) Dear Mr. Mike Kuo Hello, I am sorry for spending time many times. I would like to answer for your additional questions. Reply to Question #1: Please provide 120kHz justification by using carson rules ( 2M+2DK ). Answer 1: The attachment is the one having sent it to you as a part of manual of EUT. I calculated as follows; Description of Emission : Sound broad casting Formula : Bn = 2M + 2DK , K = 1 (typically) M = Maximum modulation frequency = 40kHz D = Peak frequency deviation = 20kHz Therefore, Bandwidth = 120kHz , Designation of emission = 120KF3E Reply to Question #2: Please provide spectrum plots to support the RF conducted output power. Please make sure to include the cable loss that used. If it is measured with power meter, please provide manufacturer/model name of power meter. Answer 1: I measured with power meter. Please refer to attach. Please correspond as soon as possible.

Question 1: Please provide emission designator and justify necessary bandwidth by using carson rules. Please refer to section 2.201 and 2.202 as guideline. Answer 1: Sorry, I forgot to describe it with your application. emission designator is "120KF3E". necessary bandwidth is "120kHz" Question 2: RF Power output section 2.1 of test report, the measured output power is listed as ERP. Is it a RF conducted output power ? if yes, what is the cable loss ? If not, please provide unmodulated RF conducted output power. Answer 2: ERP was measured by radiated. I report to you the value of unmodulated RF conducted output power.
