What is Electromagnetic Compatibility (EMC) Testing?

The concept of electromagnetic compatibility IEC 60050 (161) is equivalent to GB/T4365-1995 “Electromagnetic Compatibility Terminology”, which defines EMC as “equipment or system can work normally in its electromagnetic environment and does not constitute unacceptable electromagnetic the ability to harass.” Electromagnetic compatibility is the research that under the condit...

What is EMC test equipment

A key design challenge in designing a power bank is passing EMI testing. Electronics engineers often worry about failing EMI tests. If the circuit EMI test fails many times, it will be a nightmare. You will have to work around the clock in the EMI lab to fix problems and avoid delays in product rollouts. For consumer products such as power banks, the design cycle is short and the EMI certification...

How do environmental chambers work

Uncontrolled environmental conditions, such as temperature and humidity, may be achieved in an Environmental Chamber, which is an enclosed chamber. By delivering salt spray within the chamber, certain chambers may also imitate rusting. Temperature chambers enable manufacturers to check test their goods in a controlled environment before shipping them. This chamber’s size might vary substanti...

The difference between contact electrostatic and non-contact electrostatic

Hazards in industry: The generation of static electricity is inevitable in industrial production, and the hazards caused by it can be attributed to the following two mechanisms: 1. Hazards caused by electrostatic discharge (ESD): cause malfunction or malfunction of electronic equipment and cause electromagnetic interference. 2. Breakdown of integrated circuits and precision electronic components, ...

IEC61000-3-2 latest harmonic standard requirements and test methods

Fundamentals and Harmonics In complex periodic oscillations, both fundamental and harmonics are involved. The sine wave component equal to the longest period of the oscillation is called the fundamental wave. The frequency corresponding to this period is called the fundamental frequency. The components of a sine wave whose frequency is an integer multiple of the fundamental frequency are called ha...

How to update Microsoft Signature USB driver for Spectroradiometer and Integrating Sphere

For Windows 7/8 USB driver coding, Microsoft explicitly requires drivers to use EV code signature, and after Windows 10/11, the EV coding signature is not enough but need to submit to Windows Hardware Development Center Dashboard to get Microsoft code signature, or the USB driver can’t be run in the newest Windows 10/11 (see Fig 1) even you Disable Digital Driver Signature Enforcement.  Fi...
