Astrodyne Corporation has recently expanded its military filter product line by adding a new high performance single stage EMI filter - the LCR F19734. This EMI filter is can be used in aerospace, industrial and defense industries. “The LCR F19734, designed exclusively for use with the Excelsys Technologies’ power supplies, helps bring systems in compliance with MIL-STD 461F … [Read more...]
New Software Measures Curves of Spectrum Analyzers More Easily
New ChipScan-ESA software with numerous features has been developed by Langer EMV-Technik GmbH. This software is intended measure curves of spectrum analyzers more easily, while quickly recording data. New features of this software are believed to reduce time and money spent on measuring curves, according to the company. These available features allow users to create … [Read more...]
New Spectrum Analyzers Measure up to 8GHZ
Saelig Company, Inc. has just introduced its new TSA Range of spectrum analyzers. These are "economical USB-stick-sized miniature RF tools with large instrument performance. The PC-connected devices can perform most of the basic tests of much more expensive bench-top spectrum analyzers.” The analyzers “are nevertheless sufficient for rapid EMC analysis and for troubleshooting … [Read more...]
Addition to DSA800 Spectrum Analyzers Series
Saelig Company Inc. has just introduced its new spectrum analyzers in its Rigol Series - the DSA832 and DSA875. These analyzers are inexpensive, offer accurate in measurements, and make measurements up to 7.5 GHZ. The analyzers also include features such as tracking generators built into the analyzers, a VSWR measurement toolkit, sets of attenuators for completing work at … [Read more...]
New Connectors for Military Vehicles Depend on Integrated EMC Filters
Amphenol, a manufacturer of interconnect products for the military, commercial aerospace and industrial markets, approached MPE Ltd of Liverpool last year with a view to developing a ground-breaking range of connectors with integrated EMC filtering. So, in conjunction with Amphenol, MPE has produced the Rhino range of filtered connectors to deliver a high level of EMC … [Read more...]
The Need to Develop a Standardized Program for the Education and Training of Electromagnetic Compatibility Engineers
Anthony A. DiBiase There is an evolution in the study of electromagnetic field effects on electrical and electronic products and systems. It is progressing from an engineering art to an engineering science. This is in part due to the fact that the electromagnetic field source environment is increasing in complexity along with a greater intensity. The complexity and … [Read more...]
The Annual IEEE EMC Show – Why Dresden? Plus Proof of the Arbitrary Selection of Automotive Amplifier Harmonic Limits
Read other posts in the "Elephant in the Test Room" series here.It is looking good for using 3D software to diagnose the performance of the radiated emissions test fixture. Should get the go ahead any day now. Meantime, let’s explore this year’s hot topic. The Annual IEEE EMC Show - Why Dresden?It is no surprise that some USA residents in the EMC industry are wondering why the … [Read more...]
Avoid the Most Common Failures with These 7 Essential EMC Design Rules
A reader recently asked me what the top design rules were that they could implement on their product to maximize the chances of passing FCC and CE testing. There’s no doubt that there are countless ways to fail emissions and immunity tests, but a pattern of failure modes did emerge at my EMC lab.Regardless of the type of product I was testing, be it medical, industrial, … [Read more...]
A Report from the Southeastern Michigan EMC Fest
I recently attended the Southeastern Michigan EMC Fest, so this posting is dedicated to the show. I have a lot of admiration for Scott Lytle (Chapter Chair) and the Southeastern Michigan chapter he runs, so I decided to attend this year’s EMC Fest. The key attraction was Doug Smith, who gave attendees the benefit of his wisdom on diagnosing automotive EMC issues.The … [Read more...]
Linearization of EMC Amplifiers and Fixing the Broken Automotive Emissions Test Fixture
Read other posts in the "Elephant in the Test Room" series here.Linearization of EMC AmplifiersThis section of the posting got a little long-winded but it at least serves two purposes. It is a step closer to closing Elephant in the Test Room #2 ‘Disharmony in Harmonic Limits,’ and it also helps determine the linearization target on the TWT amplifier we are working with.The … [Read more...]
