From: Mcburney, Ian [mailto:[email protected]] Sent: Thursday, July 05, 2012 10:13 AM To: [email protected] Subject: [PSES] FCC maximum frequency measurement Dear Colleagues; I am trying to establish the maximum measurement frequency for radiated emissions for a digital device that is an unintentional radiator (part 15). Is it set by the highest frequency generated internally in a microprocessor or DSP or is it the maximum frequency that is tracked "chip to chip" on a PCB. Some of our components have high frequency internal clocking relative to PCB tracked clocking.
