EMC Radiated Testing

Conducted currents and their manner of development and propagation are another area of concern for electrical engineers lies with radiated fields. The manner in which propagation of a radiated field occurs is through a dielectric that is capable of supporting field propagation. The dielectric that is most familiar to us is free space. Water is also a dielectric that supports field propagation as well as the material used to construct a printed circuit board.

EMC General Approach to Troubleshooting

The only way to know if a system has excessive emissions or is susceptible to an external RF event is by testing. There are numerous tests possible. Only an overview of popular types of tests is provided at the time of writing. There are more than 30 different immunity tests with standards written, in addition to numerous configurations and specification limits for radiated and conducted emissions. Determining the appropriate test standard required for the product and how to perform the test in a manner that is repeatable can become a formidable task.

EMC Immunity Testing

For immunity testing, one needs to understand what the system does and how it does it. If the system resets during an immunity test, then one may need to examine the RESET line on a PCB. Many times, in attempting to resolve an immunity problem, one must force an error condition to occur. The purpose is to find the main noise entry point. This can be accomplished by disconnecting cables or loads and by shorting inputs. Using localized noise sources with hand-held probes is useful to discover entry points. For both immunity and emissions tests, isolating circuit sections or devices by breaking or shorting out signal paths can be one approach to use. Remember to keep in mind the basic facts regarding testing and troubleshooting. Magnetic fields are caused by low impedance and changing current circuits while an electric field is caused by high impedance and changing voltage circuits. The human body is a dielectric and conductive to electric fields; it reflects and absorbs electromagnetic radiated fields. Sources are characterized by their amplitude and spectrum content (waveform) while victims or receptors are characterized by their sensitivity level and bandwidth. The terms source and receptor are relative terms.

EMC Component Diagnostic Tools

A combination of components such as a ferrite bead in series with a resistor or an inductor in series with a capacitor works extremely well in helping reduce RF energy within a transmission line or PCB trace. The best filter circuit is one that is placed in series.

Printed Circuit Passive Components

Resistors are ubiquitous. Because of this their performance is taken for granted; provided they are operated within their power, voltage and environmental ratings this is reasonable, since after millions of accumulated resistor-years experience there is little left for their manufacturers to discover. But there are still applications where specifying and applying resistors needs to be handled with some care.

Training for Ethical Hacking and IT Security

For becoming a certified ethical hacker, one has to clear the certification exams after going through a professional ethical hacking training conducted by various countries worldwide. For this, a professional ethical hacking training is required in which a candidate is taught about the A to Z penetration testing mechanism. The main focus under this training is to educate the candidate about all the pros and cons of conducting and leading a “pen test” including the important business documents needed to and after the testing. Ethical Hacking Training is available in all over the world and is very famous among Design and Development (DAD) community.

EMC Test Facilities

Electromagnetic measurements must be conducted under specialized conditions for both emission and immunity testing. Whether the purpose of the test is for certification to a regulatory standard, customer requirement, or troubleshooting, testing must be performed in an environment that allows for measurement to occur without disruption from external ambients. This chapter provides insight into various types of facilities available to the test engineer, regardless of the type of measurement to be taken. It is difficult to troubleshoot a problem area when undesired signals from broadcast stations (AM/FM radio, televisions, personal communication equipment, etc.) occur at the same frequency as the signal of interest being measured in an open or uncontrolled environment.
