Fundamental Oscilloscope Probes
As electronics have become more advanced, so has the equipment used to measure their signal behavior and system performance. In the realm of EMC compliance, oscilloscopes are one of the important tools used to measure signals, hunt down noise sources, and identify time-domain measurements that may contribute to radiated or conducted emissions. Without a properly selected probe, … [Read more...]
The Voltage Rises
Santa Rosa, California, July 24th, 2023 – In the past, automobiles had minimal electrical systems and relied mainly on mechanical systems. Today, there are many electrical functions such as seat heating and cooling, comfort systems, and assistance systems that draw a lot of electricity from the battery. In a 12V vehicle electrical system, higher and higher currents must flow. … [Read more...]
Radiated Emissions Testing
INTRODUCTION Radiated emissions testing is only one part of emissions testing. CISPR 32, the document that lays out limits and methods of measurement for emissions (radiated and conducted) for Information Technology Equipment (ITE), broadcast receivers and multimedia equipment is 120 pages in length.

Placing a Metal Plate in Front of a EUT May Not Be Enough to Solve Radiated Emissions Exceedances or Radiated Susceptibility Failures
EXAMPLE OF AN EUT WHICH HAS FAILED RADIATED SUSCEPTIBILITY As described in reference 1, the EUT was exposed to a radiated immunity test at a level of 20V/m. The side which contained a vertical metal plate, with an approximately 0.3m x 0.3m dimension and which was electrically isolated from a metal baseplate failed at 12V/m and 300MHz. On the other sides of the EUT, … [Read more...]
A Short History Of A Few ITEM Issues
1977 My first issue of ITEM (Interference Technology Engineers Master) is from 1977. Was this the first issue of ITEM? No, it was not. However, it was my first issue. Why? I got my start in EMC in 1976 while working for the US Navy and was too late to get the 1976 issue. I graduated from college in 1975 and moved from Code 2330 (Nuclear Controls Engineering Division) at Mare … [Read more...]
5 Ways to Eliminate Ground Loops – Part 1
A Brief Introduction Most workers already know that proper grounding is a fundamental safety precaution for all kinds of electrical equipment. However, it’s less well known that while grounding can prevent and resolve many safety and power issues, improper grounding can create problems in data logging, data acquisition, and measurement and control systems.
