3.5.2 Cable Connections
The DS3 subtending card on the subtending host MC connects directly to the DS3 system I/O card
on the subtended mode MC. You should add ferrites to the DS3 75-ohm coaxial cables that you use
to cable the DS3 subtending card to the DS3 system I/O card. Doing so reduces the radiation/EMI
susceptibility of the system to high frequency noise, bringing it to a value between 30 and 200 MHz.
