How can power FTU EMC pre-testing be quickly screened?

FTU's rapid EMC pre-test screening utilizes low-cost equipment and methods. Equipment includes a handheld spectrum analyzer, near-field probe, ESD gun, and EFT generator. Screening items include:

1. Conducted pre-scan: scanning 150kHz-30MHz using a LISN and spectrum analyzer;

2. Radiated pre-scan: scanning 30MHz-1GHz in an open area using an antenna and spectrum analyzer;

3. Immunity screening: performing ESD contact discharge at 4kV and EFT power port tests at 2kV.

Rapid remediation: immediate modification of identified problems, such as adding filters or shielding. Pre-testing can identify over 80% of EMC problems in advance, reducing the risk of failure in formal testing.
