 Engineering consultant Richard Arsenault says the biggest problem for AM reception during the daytime “is no longer interference between stations”, as it was when the AM service was established decades ago. The former station owner and consulting engineer says the threat is now “interference from electronic devices and power lines”, and it’s steadily getting worse. [...]  At the production test facilities of a major circuit fabricator, it was dance time – all the time! This company fabricated garage door openers by the thousands, and put them through their paces on a neat row of test positions. The problem was, one tester would open his “door”, and his neighbor’s “door” would go [...]  LBA now offers users the convenience of USB and Ethernet access to systems under test in its popular EMFaracage® electromagnetic shielded chambers. Fiber optic signal isolation requires no compromise to the faraday cage isolation, or to the data stream. The picture shows an FC-10 lab top RF shielded chamber equipped with a wide bandwidth fiber [...] LBA Technology has restructured its operations to include a new Test Equipment Group. The new group will take responsibility for existing test products manufactured or sold by LBA. It is also in the process of activating major new third party test equipment distribution agreements under the Group. According to Jerry Brown, President of LBA Technology, [...]  There are several proactive steps to coping with external RF interference that start with selection of the facility design. An RF survey of a new location or problematical facility is a first step. An LBA NARTE Certified Electromagnetic Compatibility Engineer will visit the location and inventory potential on and off site RF interference sources. He [...]  Diagnostic tests are an invaluable tool in identifying patient problems. The results must be accurate if the diagnosis is to be correct. The tests are often too expensive to be repeated, and facilities are in too high demand to tolerate scheduling changes to accommodate repeat procedures. This is particularly so if they are due to [...] |
