[SI-LIST] Need some help...Conducted RF immunity test...

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.

Tom Robinson
