3-6 Amplifier Setup

STARLINE Cable Simulators

STARLINE cable simulators, model SCS-*, are used in place of fixed equalizers in systems where: (1) the amplifiers are located close together, (2) there are large amounts of flat loss from passive components, or (3) it is necessary to compensate for reverse cable tilt. The simulators fit in the same location as the equalizers.

Table 3-2 and Figure 3-2 help you choose the correct simulators.
