Issues & Answers: Testing Challenges for Electric Vehicle Testing
Standardization for EV testing continues to evolve. Tim Horacek, Product Manager of AMETEK CTS discusses trends, challenges and development of testing standards for electric vehicles.
Interoperability Testing for Connected Products and the Internet of Things
The growth of connected products and the Internet of Things (IoT) presents many challenges and risks to manufacturers and developers.
Let’s Talk About Selecting Software for EMC Emissions & Immunity Testing
There are many benefits to semi or fully automated electromagnetic compatibility (EMC) emissions and immunity tests. Product developers and test facilities alike are always looking for ways to improve their dat... Read More...
Let’s Talk About Obtaining NRTL Approvals More Effectively
The usual experience when working with a NRTL is that projects are, more often than not, late, costs are overrun, and certification reports often inaccurate. This is not always the fault of the NRTL.
Closed Loop Radiated Immunity 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.
Standards for Information and Communications Technology (ICT) Surge Protectors and Protective Circuits
The standards reviewed here have been developed to help ensure that ICT circuits will be adequately protected against surges, especially those due to lightning.
Antenna Selection for IEC 61000-4-3
With so many different antenna options on the market, it is not always easy to understand what will work best for your application.
Factors in Selecting Programmable AC Power Sources
Many electrical testing applications require a stable power source. Instead of having a custom design for each application, the programmable power supply (PPS) allows users to adjust the output frequency (F), v... Read More...
New Methods of Air Ionizer Performance Testing
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.
Proper Probe Practice is Paramount in Practical Systems
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.
