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. For more information, refer to the
