Hardware EMC test cases and test criteria

EMI Strategy
RE 30M-40G
index
CE: 30MHz-6GHz, FCC: 30MHz-5 times the frequency of the highest frequency point of the device. NEBS: 30MHz-16GHz. ITR9: 10KHz-18GHz(CLASSA,), 30MHz-1GHz should meet CLASSA, QP detection, completed in a 10m half-wave anechoic chamber, 1-18GHz should meet CLASSA, PK and AV detection, completed in a 3m full-wave anechoic chamber, signal lines should be used Shielded cables, except for ITR9, are not grounded at the far end, and the other cables must be grounded.
EMI Strategy
THIS 0.15M-30M
index
DC: 0.15KHz-30MHZ. CE certification and ITR9 certification: CLASSA. Signal port: 0.15KHZ-30MHZ, (CE certification: CLASSA. ITR9: CLASSB.) The signal line should use shielded cable, except for ITR9, the remote end is not grounded, and the other requires the cable remote grounding.
EMS Strategy
RS 80M-6G
index
CE full frequency band: 10v/m; ITR9: 800M-960M. 1400M-2000M is increased to 20v/m, other frequency bands are 10V, the criterion is A, and door opening test is required. 15HZ-10KHZ magnetic field immunity: 10mA/m.
EMS Strategy
CS 150K-80MHZ
index
Full frequency band, 10 V, A criterion.

EMS Strategy
EFT/B 1.0KV (criterion B) 2KV (criterion B)
index
Signal port 1.0KV (criterion B) Power port: 2KV (criterion B)
EMS Strategy
DC/AC-DIP Slow change, fall, interruption
index
Gradual change grade: 120% and 80%, duration 100ms, 300ms, 1s, 3s, 10s. Drop level: 70% and 40%, duration 1ms, 3ms, 10ms, 30ms, 100ms, 300ms, 1s. Interrupt level: 0%, duration: 1ms, 3ms, 10ms, 30ms, 100ms, 300ms, 1s
EMS Strategy
