Cable Requirements for EMC Compliance
Select and install cables for the NI-9229 with BNC in accordance with the following
requirements:
■
Install a clamp-on ferrite bead (NI part number 782801-01) on the BNC cable
for each channel that you are connecting to on the NI-9229 with BNC.
■
Clamp-on ferrites must be connected to the BNC cable as close to the
module as possible with a full turn as shown in the following figure. Placing
the ferrite elsewhere on the cable noticeably impairs its effectiveness.
