Re: [PSES] EMC co-location distance question

Here is the problem with the ‘2 dB rule’. If there are only two ports it simply makes more sense to cable the ports. If the device passes, go no further. If you only fill one port, then you have to still fill the remaining port to meet the 2dB rule, even if it passes. So, why waste the time?

Re: [PSES] EMC co-location distance question

Actually, C63,4:2014 is the FCC referenced standard now, not C63.4:2003. So, the 2014 edition should be used. In any case, the FCC generally requires that at least one of each type port be filled on the EUT and a minimum of at least of the different type 2 ports be filled on a host that is not

Europe is dealing with separate and sovereign countries, so MRA and the like between certifiers in all countries are needed. But, if you go to one test house in one country and another test house in that same country, even in Europe, I am sure you will find that they do not all 'accept' each other

Re: [PSES] FCC EMI Test and Ferrites on Cables

The designer is flat wrong. 15.27 makes it clear that if such a 'special accessory' is required for compliance of a device the they either must be provided with the device or they must ensure a method such that the special accessory is provided to the user of the device without additional charge an

Re: [PSES] radiated emissions testing may understate actual emissions, an example using a class D stereo amp

While there is a distance difference between Class A and Class B, it is not the distance that defines the Class, it is the Class that defines the distance. The definition of a Class B is similar, but not exactly the same as for EN. Class B part 15 digital devices are defined as " A digital device

Re: [PSES] radiated emissions testing may understate actual emissions, an example using a class D stereo amp

I do not want to speak for Mike Violette, but what I think he is referring to by interference is the fact that, while the FCC could care less if two part 15 devices interfered with each other, they do care if part 15 devices interfere with licensed services. And it is in this area that the 'issue h

Re: [PSES] Foam Table Documentation

Hi Michael The FCC is not going to state any specific table material requirement. While they recommend material like XPS (Styrofoam - an extruded polystyrene foam) above 1GHz, the only requirement is that the table be non-conductive at whatever frequency you are measuring. ANSI C63.4 says

Re: [PSES] Concerning FCC classification of digital devices

HI Neils Your client should understand that it is not his point of view that matters, it is what the FCC says about the device and what they say needs to be done in order for the device to be authorized. The simple fact that it can, at any time, connect to a PC and download software makes this a

Re: [PSES] FCC draft comments on WiFi operation in channels 12 and 13

Michael gives a good over view of the situation. The bottom line is that a device CANNOT transmit on any frequency that it has not been shown to comply. So, even if the device passive scans, it still cannot transmit on channels 12 and 13 unless those channels have been shown to comply in the appl

Re: [PSES] Job Opening for EMC Engineer

I tend to agree with Brian's statements. I would also add that even if experience is gained in another field, it is probably not enough in the EMC field to meet the " they want several years of experience" criteria. After all, it is not just engineering experience they are looking for, it is sp

Re: [PSES] Standards copyright lawsuit

Probably more accurate is that we see laws we do not like and then try to find ways around them or to find loopholes that apply to us. Sometimes it is simply better for all if we just read and understand the intent of laws and not try to sway them in one way or the other. H not gonna happ

Re: [PSES] TCBs & FCC Shut Down

To be more specific – a TCB does not actually issue a grant, even though it has their name on it as the TCB. Only the FCC can issue a legal grant of equipment authorization and no device, except under the special conditions of marketing in part 2, can be sold or offered for sale, used or turned

Re: [PSES] USA & Canada rf emission test standards

On the second part of the question about FCC and IC having the same test standards. Canada allows the use of ANSI C63.4 however, ICES-003 does say that is must be the latest addition. This only means that if both FCC and IC are being done, then the 2009 version would be the one used. As with th
