How can EMC pre-testing of intelligent low-voltage monitoring units be quickly screened?

Time：2026-02-09 Views：16次

Share：

EMC pre-testing rapid screening utilizes low-cost equipment and methods. Equipment: Handheld spectrum analyzer, near-field probe, ESD gun. Screening items:

1. Conducted pre-scan: 150kHz-30MHz;

2. Radiated pre-scan: 30MHz-1GHz;

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

Rapid remediation: Immediately correct any problems found. Pre-testing can identify most EMC issues in advance, reducing the risk of failure in formal testing.
