Voltage to Current Correlation for CDM Testing

It is now well known that testing for CDM ESD evaluation is becoming a bigger challenge. An alternate approach called capacitively coupled transmission line pulsing (CCTLP) offers advantages over standard field-induced CDM testing.

Troubleshooting EMI Like a Pro

Using RF Monitoring Probes to Troubleshoot Transient Failures

In large systems, such as big cabinets housing numerous electronic components, employing the near-field probe method can be time-consuming and, depending on the voltage level, potentially unsafe (for instance, when dealing with high-voltage circuits requiring isolation). In such scenarios, an alternative approach is necessary.
