Automotive Transient Generator System Avoids Test Set-up Problems
The TGAR transient generator system from AR adapts easily to the various requirements of different auto makers. Each automotive standard has from 5 to 30 transients that must be performed. With the TGAR system, there is no need to move the DUT to different test stations. An onboard oscilloscope simplifies pulse verification and self-calibration. LabView-based software and a … [Read more...]
Improving the Way We Measure Insertion Loss
A proposed set of new test methods may provide more accurate attenuation data Kermit O. Phipps, Philip F. Keebler, Bradford R. Connatser Many commercial and industrial electrical environments contain equipment that is sensitive to radio-frequency (RF) interference. Theft detectors, digital sensors, and medical-telemetry systems have all been known to malfunction in the … [Read more...]
EMC in Space …
Successfully dealing with EMC in space systems requires strong EMC engineering Daryl Gerke, PE, and William Kimmel, PE Many of us in the EMC business came of age during the “space race” of the 1950s, 60s, and 70s. We well remember names like Sputnik, Mercury, Gemini, and of course, Apollo. Some of us in the EMC business have even been fortunate enough to spend some (or all) or … [Read more...]
Interference to On-Board Computer Eyed as Cause of Airbus Plunge
The Australian Transport Safety Bureau (ATSB) has issued a preliminary report indicating that the accident involving a Quantas airbus flying from Singapore to Perth was likely caused by spurious information being sent to the flight control computer. The Australian safety “watchdog” is investigating whether transmissions from the Harold E. Holt Naval Communications Station … [Read more...]
