CISPR Publications 24 and 35 allow radiated and conducted immunity tests to be performed using I% or 4% steps. This article looks at measured radiated immunity test data to determine the typical shapes of radiated susceptibilities for multimedia equipment. The authors consider what those shapes tell us about the validity of the 4% step method.
Element Materials Technology has expanded its product qualification testing (PQT) capabilities at its testing sites in Hull and Hitchin (UK) to address the broader range of wireless technology requirements.
It’s imperative for successful completion of a testing project that as a compliance engineer or technician leading a product certification effort, you trust but verify the work of testing facilities.
Antennas used for EMC testing possess several characteristics which make them ideal for use in a fast-paced, production-like EMC test environment. This article will briefly describe what these characteristics are, starting with the most important parameter – antenna factor.
If you’re performing commercial conducted radiated immunity tests strictly by the book, you will want to utilize a radio-frequency (RF) signal generator and power amplifier combination that fully complies with IEC 61000-4-6.
CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.
Cable discharge events occur more frequently than we think, but they often go unrecognized or undiagnosed for root causes, resulting in unnecessary device failures. This article discusses the origins of three types of cable discharge events.
In this second part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in the European Union for radio modules and equipment which contain radio modules.
Without much effort and expense, it is possible to perform pre-compliance testing in a manner that saves considerable time and money without commercial or financial risks associated with purchasing a full-compliance test facility.
