FAQ

Product-specific questions

Product-specific answers based on available technical information.

How does SHC68-68 differ from SHC68-68-EPM?

SHC68-68 has basic assembly shielding without shields separating analog and digital signals. The EPM design adds shielding and specific wire pairings.

Which PXIe-6349 connector uses SHC68-68?

NI recommends SHC68-68 for Connector 1 and SHC68-68-EPM for Connector 0. NI permits SHC68-68 on both connectors when the application does not require Connector 0 digital I/O.
