The EMC Blog

- January 31, 2014

Arturo Mediano is a professor at University of Zaragoza (Spain) and founder of The HF-Magic Lab®, a specialized laboratory for design, diagnostic, troubleshooting, and training in the EMI/EMC/SI and RF fields. He is also an instructor for Besser Associates (CA, USA) offering public and on site courses in EMI/EMC/SI/RF subjects. In The EMC Blog, he'll provide interesting and useful information about EMI and EMC, including real-world circuits, waveforms, and design/troubleshooting techniques, interesting tools and instruments on the market, as well as EMI/EMC conferences and symposia around the world.

Platform interference

  • 12.18.2015

Every manufacturer seemingly wishes to add some form of wireless capability into new and existing mobile, household, industrial, scientific, and medical product. This trend toward the “Internet of Things” is in full swing and with it comes problems with EMI. That is, EMI from the product itself, that interferes with sensitive telephone, GPS/GNSS, and Wi-Fi/Bluetooth receivers. This is called “platform interference” and it’s a big problem for manufacturers.Read More...


Review: Rohde & Schwarz FPH spectrum analyzer

  • 12.07.2015

Rohde & Schwarz (R&S) recently released their new affordable handheld spectrum analyzer, the model FPH “Spectrum Rider”. We'll be reviewing this here.Read More...

Review: Tekbox LISNs

  • 11.28.2015

Tekbox Digital Solutions recently introduced LISN models for both line-operated and DC-operated equipment. I’ll be reviewing their model TBLC08 (line-powered 50uH LISN) and model TBOH01 (DC 5uH LISN).Read More...

Review: Tekbox Near-Field Probes

  • 11.12.2015

A set of near-field probes is an essential tool for troubleshooting EMI issues. Tekbox Digital Solutions has recently introduced a kit containing a set of three H-field, one E-field probe, and either a 20 or 40 dB gain broadband preamplifier. All this is included in a laser-engraved wooden box - a very nice touch. The probes may also be ordered without the preamplifier. I had a chance to try them out and compare with some similar probes.Read More...


Measuring VSWR with the Rigol DSA815

  • 10.25.2015

Voltage standing wave ratio is a measurement of the impedance match of any RF component, sub-assembly instrument in reference to a standard 50-Ohm resistive impedance. This article discusses how to use the Rigol DSA815 to make this measurement. Read More...


Review: Test Probes, Inc. (TPI) connector adapter kit

  • 10.12.2015

How many times have you gone to reach for a particular coaxial adapter and failed to find the right one? Test Probes, Inc., now Test Products International (TPI) has two coaxial connector adapter kits and one of my colleagues traded an extra Model TPI 3000A kit for something I had that he needed. I’d like to describe this remarkable adapter kit. Read More...

Review: Picotest J2150A harmonic comb generator

  • 10.08.2015

Picotest has just introduced a very unique harmonic comb generator (Picotest calls it a harmonic injector) that’s not only designed to reveal resonances in power supply and voltage bus designs (power integrity), but also has interesting uses in EMC measurement and troubleshooting. It also has several unique features that really set it apart from all other comb generators.Read More...


Review: Seikoh Giken optically-coupled E-field probe

  • 09.22.2015

The Siekoh Giken OEFS (Optical Electric Field Sensor) optically-coupled E-field probe is a very unique instrument. The company has developed a technology whereby the amplitude and frequency information from E-fields may be captured and transferred via optical fiber and reconverted to an RF signal. The optical fiber allows E-field measurements to be made non-invasively.Read More...
