Return loss is better than 20dB from 1 GHz to 6 GHz and better than 15 dB down to 700 MHz. The loss is typically associated with antennas. The signal is fed in through barrel connectors, so no loss there. Test frequencies supported are from 700 MHz to 6 GHz.
Thank you for today. My two questions are: what is the average transmission loss of your test chamber from the outside of the box to the inside at a typical DUT frequency. And secondly, what is the ballpark worst case return loss of the interior walls at a typical DUT frequency?
So this MPE, I would want to use it simulate the OTA environment to test and understand the behavior of a 2G/3G cellular device. Is it suitable for that type of work? At this point we would not be using it for studying MIMO, and not for 802.11 (yet).
We are currently testing a 3G/2G device. The connectivity is impaired by low signal level that is further reduced by fades. Does octoscope sell a channel emulator? If so, what is the approx cost? This is not a MIMO system.
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.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
