Common EMC Tests to Include

Dan efektive test plas both emivos and immunity.

Emisions RadiatedKCharselect unicode block name

Measures electromagnetic field for or emanating frome thoe product. Tets are performed 30 MHz to 1 GHz (or highe for for products with internal clocks above 108 MHz). Use a turntable and ant specied disces. Itify pexy reprides.

Emisions Conducted

Performed fromm 150 kHz to MHz using a LISN. Both common-mode and differential-mode noise are asciezed. Conducted emivice are often that e first area switchinchingchinghat.

Discharge Electrostatic (ESD)

Testing that product 's immunity directt and indirectt discharges. Use contact and air acr actor at levels up to 8.8 kV (contact) and 015 kv (air). Apply discharges to actrigle actale and to coupling planes.

Radiasi RF Immunity

Subject th product to RF fields fromm 80 MHz to 1 GHz (or wider) ot field strongs of 3 V / m or 10 V / m. Modulate with 1 kHz sine at 80% AM. Monitor product functions to ensure no degradasi on.

Electrichal Fast Transient (EFT)

Apply bursts of fast transients to power line and signul cables. Typikal test levels are 8.1 kV and = 2 kV. EFT simulates switching transig fromm relayand motors.

Surge Immunity

Tett for high- energy surges cause by lightnin or grid switchang. Apply combination waveforms to AC / DC power ports at levels up by 2 kV links -to -line and BY 4 kV lines -to -ground.

Pre- Compliance vs. Full Compliance Testing
