Good quality means high coverage braid, and Charlie's note about the 360 bonding and how the shield is attached is critical and should prove successful from my past experience. The only times I failed with a good shield is when I didn't terminate the shield at both ends or poorly at one end or the other.

Regards Charlie -----Original Message----- From: Schaefer, David [mailto:[email protected]] Sent: 25 April 2012 15:47 To: [email protected] Subject: [PSES] CS116 shielding All, I am looking for some guidance on shielding for protection against the CS116 waveform. Our customer failed at as much as 20 dB down from the limit. They have a basic braid shield, but that was obviously insufficient. Anyone have a suggestion, or advice on where I may start looking?
