Starline Cable Simulators – SCS-*
The Starline Cable Simulators, Model SCS-*, are used in place of fixed equalizers in systems where the amplifiers are located close together. The simulators are designed to fit in the same location as the equalizers.
Table 3-2 helps you choose the correct simulators:
