Given that information, I clearly do not have an answer, however there is the old saying: "They are Federal Regulations, you're not _supposed_ to understand them!" Who did you talk to at the FCC? Brent
From: Grasso, Charles [mailto:[email protected]] Sent: Friday, February 13, 2004 11:23 AM To: 'Brent DeWitt'; '[email protected]' Subject: RE: Speaking of limits above 1GHz Hi Brent, Thanks for your comments. I have pasted below a response from the FCC: "Acceptance of a GTEM cell for compliance testing is addressed in Public Notice 54796 dated July 12, 1995 and in ANSI C63.4-2001. I do not have an electronic copy of the public notice, but I will fax you a copy at 303-723-3901. Since the standard OATS with which the GTEM is correlated for acceptance only covers the frequency range 30 to 1000 MHz, there is no standard for correlation of a GTEM outside this range." Hence my confusion and my qs which I repeat: If : the application is invalid because of the lack of site attenuation specifications then why does the FCC insist on testing above 1GHz? How can the data taken above 1GHz be OK for the DoC and not for qualifying a GTEM Best Regards Charles Grasso Senior Compliance Engineer Echostar Communications Corp.

The implied stand by the FCC is that a GTEM cannot be used above 1 GHz because the published methodology for correlation has not been proven valid in that frequency range. Rather ironic since the GTEM becomes a more valid substitute for an OATS as you go above 1 GHz.

The application was rejected by the FCC on the grounds that as there was no site attenuation requirements above 1GHz. Can some one please explain the logic? If : the application is invalid because of the lack of site attenuation specifications then why does the FCC insist on testing above 1GHz? How can the data taken above 1GHz br OK for the DoC and not for qualifying a GTEM?? For those who may not know: the FCC has published a methodology for demonstrating correlation between a GTEM and an OATS. Our GTEM meets that correlation criteria. Confused in Colorado.

EN 55022 currently calls for stopping testing at 1 GHz... Or does it? What guidlines would one follow to test a 2 GHz PC? Thanks, -- Derek N.
