The New York Times reports Apollo 10 astronauts Thomas Stafford, John Young and Eugene Cernan did hear weird sounds during their lunar orbit in 1969, but the noise was likely the result of radio interference, not extraterrestrial musicians. The strange sounds apparently emanated from interference between VHF systems on the lunar module and the command module orbiting the … [Read more...]

Frequency Selective Area Monitor Conforming to ITU-T K.83
A new measuring station, model AMS-8061 Area Monitor, is now available from Narda Safety Test Solutions. This autonomous measuring station monitors electromagnetic fields from 100 kHz to 6 GHz in up to 20 freely definable frequency bands. This allows the field exposure levels due to GSM, UMTS, and LTE as well as DAB and DVB-T to be recorded separately. The measurement conforms … [Read more...]
How To Achieve FCC Compliance in Six Steps
MET Labs explains how to achieve FCC compliance in six steps in their recent blog posting. They first explain about the need for EMC compliance and the various routes to compliance in the U.S. - verification, declaration of conformity, and certification. The six steps are outlined below: • Step 1 - select radio frequency and design equipment • Step 2 - test during … [Read more...]
Application Note: Selection and Operation of RF Power Amps for EMC Testing Apps
Instruments For Industry (IFI) has made available an application note that highlights issues when choosing a power amplifier for your immunity test applications such as regulatory burden and system loss profile. In another application note (available once the short questionnaire is filled out in the link below), IFI briefly explored the basics of how to choose a power … [Read more...]

ESA’s Mercury Orbiter Tested for EMC
ESA’s Mercury orbiter underwent electromagnetic compatibility, radiated emission and susceptibility testing last month inside the Maxwell chamber of ESA’s ESTEC Test Centre in Noordwijk, the Netherlands. If the orbiter of the BepiColombo mission seems to stand at an unusual angle above its test chamber floor, that’s because it does – intentionally so. “We are performing two … [Read more...]
Meeting the Challenge of “Universal" Coverage in the Coming 5G Era
The University of Surrey’s 5G Innovation Centre (5GIC) has recently published a white paper on potential coverage and reliability of 5G networks, especially in rural areas. Dr. Tim Brown of 5GIC, reports, "Everyone can foresee a gigantic capacity challenge for wireless networks over the coming decades. The research community is responding well by developing 5G technology in … [Read more...]
Has The EMC Directive Achieved What It Set Out To Do?
NewElectronics (UK) has written a white paper on the EMC Directive - its history, the new legislative framework and how it affected the Directive, how well it’s being enforced, and market surveillance. The EMC Directive is all about electrical interference – both emissions and immunity. As test house TUV puts it ‘Do not disturb. Do not be disturbed’. When enacted in 1989, the … [Read more...]
World Radio Day – IEC Work Supports Relief Efforts During and After Disasters
World Radio Day marks the anniversary of the first broadcast by UN Radio on 13 February 1946. “Radio in times of emergency and disaster”, the theme of this year’s World Radio Day, offers the opportunity to highlight radio’s unique contribution to help communities respond to and recover from natural disasters, crises and conflicts, or mitigate their impact, as highlighted by … [Read more...]
