This book was released on 2001 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the implementation of mode-stirred method for susceptibility testing according to the current DO-160D standard. Test results on an Engine Data Processor using the implemented procedure and the comparisons with the standard anechoic test results are presented. The comparison experimentally shows that the susceptibility thresholds found in mode-stirred method are consistently higher than anechoic. This is consistent with the recent statistical analysis finding by NIST that the current calibration procedure overstates field strength by a fixed amount. Once the test results are adjusted for this value, the comparisons with the anechoic results are excellent. The results also show that etst method has excellent chamber to chamber repeatability. Several areas for improvements to the current procedure are also identiified and implemented.
