We are currently attempting to get all our products to meet the new requirements for the EN60601-1-2-2001 by the November 1st deadline. We have all our products updated to the new requirements except for one. We have been having some difficulty with the new Conducted RF immunity test EN61000-4-6 / ENV50141 on this product. This test basically takes an AM modulated signal with a 3V level in the range of 150k to 80 meg and couples it into all I/O and power cables using a bulk current injection probe clamp. Our system is detecting the induced interference and shutting down indicating a fault condition exists. Unfortunately this is considered a failure for this test. Has anyone had any experience trying to comply to this test. We have tried filtering several critical signals to prevent the faults, but the induced signal seems to everywhere. Any suggestions would be helpful at this point. Thanking any and all in advance.
