you can use octoBox for pre-compliance EMC but you would need to rely on relative measurements (e.g. i need to get this spur down by 10 dB) rather than absolute (e.g. matching a certification lab level)
@FANNY: Thank you very much. Now, all those test Boxes to isolate testing is only for Performance. Do you use similar boxes for pre-compliance EMC? Cables are a big problem when they are passed through the chamber. They need to have the proper filter to isolate DATA (labtop running scrips and colection) and The actual TEST (investigation)
very interesting stuff. certainly a lot to consider for the future. Hopefully some other groups may create some standard testing and we can utilize the results relaiably without having to perform some of this testing on our own.
Yes, we put one device in a walk-in screen room in order to isolate the two devices. We ended up having trouble in overnight testing because we performed open-air testing at night with the transmitters on the roof. The signal from the roof-top transmitters was interfering with theovernight lab testing. We needed to add local isolation for the device outside the screen room.
On page 13, I would expect that the MPE frequency response for the 5 GHz band to be more complicated than the response for the 2.4 GHz band. This depends on the multipath conditions being the same for both bands. Is my intuition correct?
@tpyn - We would love if you promote these cources. Our server shouldn't have any trouble. You can email me at firstname.lastname@example.org . I'm the Project Manager for the CEC and we can chat about the promotion you're suggesting.
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
-The streaming audio player will appear on this web page when the show starts at 2 PM Eastern time today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. If that doesn't work, the class will be archived immediately following our live taping.
@jrc_fw - The audio archive will be available immediatley after the presentation is over. You will just need to click on the play button. The archives for the previous classes this week are already available on their classroom pages. Just click on the play buttons to hear the audio.
-You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
