10 interesting products from IEEE EMC 2016

-September 19, 2016

A few months ago, I covered the announcement for the IEEE EMC 2016 Symposium in Ottawa, Canada. Here are some of the products I found most interesting.

As always, I found going to the EMC Symposium a worthwhile trip. There were plenty of conferences, technical presentations, networking, and exhibits featuring tools and equipment for the EMI/EMC and signal-integrity practitioner. This year, they Symposium had more than 100 companies exhibiting. Figure 1 gives you a view of the exhibit hall.

Here are ten of the products I found most interesting. I've organized them into groups of like equipment so you don’t have to scroll through ten pages to see it all. Each page has links to the other pages:


Rohde and Schwarz RTO oscilloscope


If you make EMI/EMC measurements for debugging, you'll find the RTO/RTE oscilloscopes quite useful. These instruments have excellent signal fidelity and high acquisition rate to analyze your systems in both the time domain and frequency domain.

The RTO 2000 series samples at up to 20 Gsample/s, has bandwidths from 600 MHz to 4 GHz, and include up to 16-bit resolution. You can use them to find signal faults because the oscilloscopes can display 1 million waveforms/s. That's helpful for EMI susceptibility and signal-integrity troubleshooting.

In my opinion, the triggering capabilities in both time and frequency domains is one of the most useful features. Combined with up to 4 channels, you can obtain a full view of the behavior of your failing systems and locate the origin of emissions or of susceptible areas in your PCB.

I had the opportunity to try this instrument for a few days several months ago and enjoyed it. In Figure 2, you can see demo with near field probes.

Keysight Technologies EMI receiver


At the Keysight booth, I spoke with EMC business manager Mark Terrien, who explained some of the company's new products. For example, the N9038A MXE EMI Receiver (Figure 3).

This instrument is one of the X-Series signal analyzers intended for precompliance measurements and diagnostic evaluation of your designs. But, it's also a standard compliant receiver for CISPR 16-1-1 and MIL-STD-461.

The N9038A's short overall scan time with time-domain scanning enabled by fast FFT scans lets you quickly find frequencies of your equipment's peak emissions. It's user interface includes a strip chart, markers, span zoom, zoom span, and spectrograms.

Amplifier Research handheld analyzer


AR is well known for its RF solid-state amplifiers for EMC immunity and RF testing. Output powers range from 1 W to 50 kW and they cover the frequency range from DC to 1 GHz. I had the opportunity to talk with Joseph Diesso (VP corporate marketing) who kindly demonstrated many of the company's products.

I liked the new SM400K (Figure 4), a high-performance handheld analyzer designed for measuring complex or pulsed electric and magnetic fields up to 400 kHz, and broadband measurements up to 40 GHz.

The SM400K has interchangeable sensor heads. Its X, Y, and Z analog outputs let you locate the origin of emissions. Battery life is more than 70 hours and the data logger supports up to 21,000 measurement samples.

With the ARwavewARe software application, you can analyze the recorded data in both the time domain and the frequency domain. The software  provides real-time processing and post-processing capabilities.

I expect these kind of probes gain in importance in the coming years because the new regulations for EM exposure. Be prepared to use them, especially for big industrial or medical installations.
