testing

This article describes a proposed addition to the IEC 61000-4-3 standard. This addition would allow detailed testing of a product while coordinating and documenting the frequency changes of the test.

The standards reviewed here have been developed to help ensure that ICT circuits will be adequately protected against surges, especially those due to lightning.

With so many different antenna options on the market, it is not always easy to understand what will work best for your application.

Many electrical testing applications require a stable power source. Instead of having a custom...

This article defines ionization qualification and periodic verification test procedures for ionizers which are not addressed in STM3.1 or SP3.3, including air-assist bar ionizers, soft x-ray ionizers, an alternative method of room ionization, and non-airflow alpha ionizers.

If someone were to ask you what one singular device is most synonymous with testing, or even electrical engineering, the overwhelming response would most likely be the oscilloscope probe.

It is no trivial matter to properly interpret system level test results on high-speed boards. Board manufacturers (OEMs) assess the ESD robustness of their system by means of gun testing, not always in accordance with the IEC standard.

Can the hi-pot test and the insulation resistance test be combined into a single measurement? Let’s discuss each of these parameters as circuit parameters and as safety parameters.

It is a dramatic understatement to say that the world of electronic devices continues to go more portable. The mantra of smaller, lighter, and faster shows itself through the myriad of devices we use as we move through our world outside of traditional work and home environments.

For production-line testing, the 25- or 30-amp grounding continuity test is not likely to identify construction anomalies that would not also be identified by a simple low-current test.
