4. One communication port coupling/decoupling network

We offer complete EMC surge testing capabilities!

What is SURGE emc testing?

Surge (SURGE) EMC testing is an essential method to evaluate the immunity of electronic devices against sudden voltage spikes. It simULates real-world disturbances such as power failures and lightning strikes, assessing the device’s performance under harsh electromagnetic environments. For instance, it checks whether a device can continue operating normally after a lightning strike.

What is EOS Testing?

EOS stands for Electrical Over Stress, which refers to conditions where external current or voltage exceeds the maximum rated tolerance of a component. This may result in performance degradation or permanent damage to the device.
